Answer:
q2 must also be doubled
r may also be halved
Explanation:
According to Coulumbs law
F= K q1 q2/r^2
If q1 is doubled, we must necessarily double q2 and r may also be halved in order to maintain F at the same value. Once the value of F is thus kept constant and E is also constant, the product FE must remain constant.
I think the amount of force will decrease and the amount of work will increase
This is due to water pressure
