Answer:
The magnitude of charge on each is
Solution:
As per the question:
Mass of Earth,
Mass of Moon,
Now,
The gravitational force of attraction between the earth and the moon, if 'd' be the separation distance between them is:
(1)
Now,
If an identical charge 'Q' be placed on each, then the Electro static repulsive force is given by:
(2)
Now, when the net gravitational force is zero, the both the gravitational force and electro static force mut be equal:
Equating eqn (1) and (2):
Q =
