The figure below shows a small, hollow, plastic sphere hanging vertically from a thin, lightweight thread. The sphere has a mass of 7.10 g and a uniformly distributed charge of 91
Directly below it is a second sphere with the same mass, but a charge of
92 = -58.0 nC. (Assume this second sphere is fixed in place.) The centers of the two plastic spheres are a distance
d = 2.00 cm apart.

(a) What is the tension (in N) in the thread?
0.11154376
N
(b) The thread will break if the tension in it exceeds 0.180 N. What is the smallest possible value of d (in cm) before the thread breaks?
The analysis is the same as in part (a), including the magnitude and direction of the gravitational and electric forces. Note that Coulomb's law depends on the square of the distance d. Use the
threshold value of the tension to solve for d. cm
Expert Solution

Step 1
