Charge,![q_2=2.3\ C](/tpl/images/0634/2338/14c33.png)
Explanation:
It is given that,
Charge 1,![q_1=5.2\ nC=5.2\times 10^{-9}\ C](/tpl/images/0634/2338/919fc.png)
Repulsive force,![F=30\ mN=30\times 10^{-3}\ N](/tpl/images/0634/2338/c0e2c.png)
Distance between two charges, d = 60 m
We need to find the magnitude of second charge. The electric force between two charge is given by :
k is electrostatic constant
So, the magnitude of second charge is 2.3 C. Hence, this is the required solution.
