Sorry this problem has so many parts--thank you in advance for your effort.
Part (1-7)
Given:
Distance moved by charge is AB = d unit. ( Along Electric field)
Test charge is +q
Direction of Electric field is from A to B
From the defination of work =w
w= qEcosS ( where = angle between elcetric field vector and displacement vector)
S is displacement from A to B
W = q * E * cos 0° * d
( = 0° as displacement vector is along E vector)
and d =
w = (q* E * d ) J

Sorry there are so many parts to the question--thank you in advance for your effort. INVESTIGATION 1: ELECTRICAL AND GRAVITATIONAL FORCES Let's begin our discussion with the familiar expression for the Coulomb force exerted on charge 2 by charge 1, F1-2 f12 Unit vector q1 r2 ,-8.99 × 109 Ncme C2 92 where k, is a constant that equals 9.0 x 10 N m2/C2. The force F2-1 of charge 2 on charge 1 is equal in magnitude and opposite in...
Electric Potential Learning Objectives During this lab, you should be able to e understand the difference between electric potential and electric potential energy . relate electric potential energy to gravitational potential energy determine the shapes of equipotential lines for various charge configura- tions use the equipotential lines contour plots to determine the shape of the elec- tric field lines. 2.1 Pre-lab Energy has various definitions, one of which is "the capacity to do work: For a conservative force, such as...
Sorry this problem has so many parts--thank you in advance for your effort. Which Force Is Stronger-Electrical or Gravitational? Let's peek into the hydrogen atom and compare the gravitational force on the electron due to interaction of its mass with that of the proton to the electrical force between the two particles as a result of their charges. In order to do the calcula- tion, you'll need to use some well-known values: Electron: me-9.1 × 10-31 Kg qe =-1.6 ×...

Sorry this question has so many steps--Thank you in advance for the extra effort:) Before proceeding with the video analysis, you will need to determine how the force the prod exerts on the hanging ball (the Coulomb force, F.) depends on 10 REALTIME PHYSICS: ELECTRICITY AND MAGNETISM the position of the hanging ball. This will allow you to calculate the values of the Coulomb force using the data from your video analysis. The situation is shown in the diagram below....
I. igure is a map showing force lines and equal energy contours for a plane in a conservative field. The energy contours have units of J/kg. This means that the amount of energy transferred to/from the field as an object is moved depends on the mass of the object. This also means that the force acting on an object depends on the mass of the object. (a) If an object is moved from a position where its centre of mass...
Please help, I am struggling! A Cycloidal Path A particle with mass m and positive charge q starts from rest at the origin as shown in the figure below. There is a uniform electric field = Eo? and a uniform magnetic field B = BoZ The path of the charged sketched below is a cycloid whose radius of curvature at the top points is twice the y-coordinate at that level. This path is exactly the same as the path of...
The figure shows a fixed (non-moving) charge Q > 0 and four points, A, B, C, and D. Points A and D are the same distance from charge Q and points B and C are the same distance from charge Q. Point B is directly between point A and Q and point C is directly between point D and Q A +Q The dashed lines are on circles centered at the charge Q. A) (GR, PS) A proton (interacting with...
A particle with a charge of q = 13.0 PC travels from the origin to the point (x, y) = (20.0 cm, 50.0 cm) in the presence of a uniform electric field E = 250 V/m. Determine the following. (a) the change in the electric potential energy in )) of the particle-field system If an object is acted on by a conservative force, how is the change in potential energy related to the work done on the object by a...
1. A particle with a charge of +4.20 nC is in a uniform electric field E⃗ directed to the negative x direction. It is released from rest, and after it has moved 6.00 cm , its kinetic energy is found to be 1.50×10−6 J . a. What work was done by the electric force? b. What was the change in electric potential over the distance that the charge moved? c. What is the magnitude of E? d. What was the change...
