Numerical Questions
1. Two small charged spheres are separated by a
distance of 30 cm in air, whose charges are
2x10-7C and 3 x 10-7C respectively. Calculate
the force between them.​

Answer 1

Answer:

F = 6 x 10^-7

Explanation:

F = K Qq/r²

F = 9 x 10^9 x  (3 x 10^-7) x (2 x 10^-7)     [K = 9×10^9 (experimental value)]

                              30²

  = 9 x 10^7 x 6 x 10^-14

  = 6 x 10^-7
