Gordon the night custodian dusts off a classroom globe with a feather duster, causing the globe to acquire a charge of -8.0 x 10°C. What is the magnitude and direction of the electric field at a
point 0.40 m from the center of the charged globe?

The rate at which work is done is called power.

Explanation:

The rate at which work is done is called power. It is also known as rate of doing work. Mathematically, it is given by :

Where

W is the work done by the force

t is the time taken

Since, W = F × d and

So,

The SI unit of power is watts.

Hence, this is the required solution.
