According to coulombs law, how is the electric force related to the distance between two charges?
a. the electric force is directly related to the distance.
b. the electric force is indirectly related to the distance.
c. the electric force is directly related to the square of the distance.
d. the electric force is indirectly related to the square of the distance.

D

Explanation:

From the formula of coulombs law F = Kq1q2/square of r, we can say the electric force is indirectly related to square of r

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
