Explanation:
power=f×v. recall= distances/ time
= f× d/t
= 30 × 2/5
=12watt
Here we can use coulomb's law to find the force between two charges
As per coulombs law
]tex]F = \frac{kq_1q_2}{r^2}[/tex]
here we have




now by using the above equation we have


so here the force between two charges is of above magnitude and this will be repulsive force between them as both charges are of same sign.
I think it’s 15cm
Might be 7cm
The correct answer is C) Rainfall
Acceleration due to gravity.
