The impulse J is equal to the magnitude of the force applied to the cannonball times the time it is applied:
But the impulse is also equal to the change in momentum of the cannonball:
If we put the two equations together, we find
And since we know the magnitude of the average force and the time, we can calculate the change in momentum:

Answer:
Charge on each metal sphere will be
Explanation:
We have given number of electron added to metal sphere A
As both the spheres are connected by rod so half -half electron will be distributed on both the spheres.
So electron on both the spheres
We know that charge on each electron
So charge on both the spheres will be equal to
So charge on each metal sphere will be equal to
