The relationship between the electric force and the charge on the spheres will be determined by adjusting the voltage on the spheres while keeping the separation distance r between the spheres constant. Q = CV where C is the capacitance of a charged sphere (we'll study capacitance later, just know that Q a V) and the relationship between V2 and the twist angle is linear, what does that say about the relationship between the magnitude of charges O and the...

(1) Two conducting hollow balls of diameter 3.75 cm are both initially charged by a bias voltage of +5000 V. When they are brought to a center-to-center distance of 10.0 cm, what is the electrostatic force between them? (2) For the torsion balance, write the relationship between the exerted force and the angle of rotation. (3) For the two conducting balls as described in problem 1, when one ball is attached to a torsion balance the wire is twisted by...

Coulomb’s Law
A massless sphere of charge q1 = 0.640 µC is at the end of a
spring in equilibrium as shown below in figure a. When a charge q2
= -0.410 µC is held beneath the positively charged sphere as shown
in figure b, the spring stretches by a distance d = 3.60 cm from
its position in figure a. When equilibrium is reestablished, the
distance r between the charges is 5.20 cm. What is the spring
constant of...

The relationship between the electric force F (e) and the gravitational force F (g) (or 1. weight) between two electrons. Two equal and equally charged spheres of 0.1 g of mass each are suspended from the same point by threads of 13 cm in length. Due to the repulsion between both, the spheres are separated 10 cm as seen in the graphic representation. Find the load of 2. each of them. Calculate the number of electrons that add an electric...

A molecule of DNA (deoxyribonucleic acid) is 2.18 μm long. The ends of the molecule become singly ionized: negative on one end, positive on the other. The helical molecule acts like a spring and compresses 1.06% upon becoming charged. Determine the effective spring constant of the molecule. ______N/m Two small identical conducting spheres are placed with their centers 0.59 m apart. One is given a charge of 12 ✕ 10−9 C, the other a charge of −17 ✕ 10−9 C....

As you discussed in Activity 2.10, Relationship 2 of the Particle Model of Matter gives the relation between the force acting between two particles and the potential energy due to this force: the force is equal to the derivative of the potential energy with respect to the particle separation. The force is always in the direction that lowers the potential energy. 3) a) The electrical force between two positively charged objects is always repulsive and becomes weaker as distance increases,...

In reality, the magnitude of the force between the two spherically symmetrical charge distributions is described by Coulomb’s law F= (kq1q2)/d^2 where k is a constant equal to 8.99×109 Nm2/C2, q1 and q2 are the magnitudes of the charges, and d is the distance between the centers of the spheres. Assuming that both spheres have equal charges, estimate the charge on each sphere, using the first data point in your table. Remember that, for the calculations to be correct, both...
