Question

Two insulated charged copper spheres A and B have their centres
spo separated by
a distance
50 cm.
What is the mutual
force of
electrostatic repulsion if
the charge
each is 6.5× 10^-7C ? The radii
of A and B cre negligible
compared to the distance
of separation
​

Answer 1

Answer:. 0.015N

Explanation:

By coloumbs law

F=kq1q2/r^2

F=(9×10^9×(6.5×10^-7)^2/(50×10^-2)^2

F=0.015N
