(a) A physics lab instructor is working on a new demonstration. She attaches two identical copper spheres with mass m = 0.180 g to cords of length L as shown in the figure.
A
Both spheres have the same charge of 6.80 nC, and are in static equilibrium when
=
4.95°. What is L (in m)? Assume the cords are massless.
0.150
Draw a free-body diagram, apply Newton's second law for a particle in equilibrium to one of the spheres. Find an equation for the distance between the two spheres in terms of L and 0, and use this expression in your
Coulomb force equation. m
(b) What If? The charge on both spheres is increased until each cord makes an angle of 0 = 9.90° with the vertical. If both spheres have the same electric charge, what is the charge (in nC) on each sphere in this case?
13.6
☑
Use the same reasoning as in part (a), only now, use the length found in part (a) and the new angle to solve for the charge. nC
