Question

Two identical charges kept 2 m apart in vacuum exert forces of magnitude 36 x 10-9N on each other. The charge on each of them is ​

Answer 1

Answer:

F = K q1 × q2 / R*2 ... K = 9 × 10*9

take q1 = q2 = q and then solve after putting the values , R = 2m ... Ans is q1 = q2 = 4 × 10*-9 C or

4 nC
