potential energy of charge particle
PE = Q*V
=> 500 = Q*20
=> charge of particle , Q = 25 C
What is the answer why? If 500 J of work are required to carry a charged...
If 500 J of work are required to carry a charged particle between two points with a potential difference of 40V, the magnitude of the charge on the particle is: a) 0.040 C b) 12.5 C c) 20C D) cannot be computed unless the path is give e) none of these My solution: I used the equation V=W/q inorder to solve for the charge. I plugged in the numbers to get 40= (500)/X. The answer I got was .08. According...
I would really appreciate if someone answer these question. Thank you. A charged particle moving in the presence of both an electric and magnetic field moved in a closed path (i.e. a path that begins and ends at the same point). If the energy of the particle at the end of the closed path is 2.0J greater than its energy when it began the path, which of the following statements is correct? a. The magnetic field performed 2.0 J of...
Electric potential difference EM 105 B. Shown at right are four points near a positively charged rod. Points W and Yare equidistant from the rod, as are points X and Z. A charged particle with mass m3x 10 kg is released from rest at point W and later is observed to pass point X 1. Is the particle positively or negatively charged? Explain. 2. Suppose that the magnitude of the charge on the particle is 2 x 10 C and...
Help in part C. Please. (c) How much work is required to quadruple the separation? (J) A parallel-plate air capacitor has a capacitance of 920 pF. The charge on each plate is 1.80 mu C. What is the potential difference between the plates? V If the charge is kept constant, what will be the potential difference between the plates if the separation is quadrupled? V How much work is required to quadruple the separation? J
please give me reasons why answer C is correct and the others are incorrect 20. A charged particle has a charge of q+2e and a mass of 4.00 u, where u is the atomic mass unit, with 1 u 1.661 x 10-27 kg. Suppose the charged particle travels in a circular path of radius 4.50 cm in a uniform magnetic field with B- 1.20 T. Which of the following is TRUE? A) The particle's speed is 1.30 × 105 m/s...
l unnohm electric field. What is the magnitude of the electric field? If this charge is removed and a 5 μC charge is placed at the same point instead, what force will it feel? 2. 800 J of work is required to move a charge between two points with potential difference of 40 V. Wha is the magnitude of the charge? iuo (ach 2 HC), are arranged at the corners of a s
can you answer all questions please? 1.) The figure below shows a small, charged sphere, with a charge of +38.0 nC, that moves a distance of d 0.196 m from point A to point in the presence of a uniform electric field E of magnitude 290 N/C, pointing right. A positive point charge q is initially at point A, then moves a distance d to the right to point B. Electric field vector E points to the right. (a) What...
A charged particle moving through a magnetic field at night angles to the field with a speed of 24.7 m/s experiences a magnetic force of 2.78 x 10 N. Determine the magnetic force on an identical particle when it travels through the same magnetic field with a speed of 5.44 m/s at an angle of 31.20 relative to the magnetic field. x How does the magnetic force acting on a charged particle moving through a magnetic field depend on the...
this is one question with many parts, thanks for the help! D. Imagine a negatively charged particle (9--0.2 C) free to move back and forth along a straight line. There are other nearby charged particles that create electric potential and electric field at all points on the line. The system is made up of the negatively charged particle and the other particles that created the potential and field. As usual, we will assume an isolated system, so that this system's...
The speed is 3.9270E4 The force is 3.607E-15 The distance from the point of injection to the detector is .10789 A particle of mass 1.2616 x 1025 kg and charge of magnitude 3.2 x 10-19 C is acceler- ated from rest in the plane of the page through a potential difference of 304 V between two parallel plates as shown. The particle is in- jected through a hole in the right-hand plate into a region of space containing a uniform...
