A 7.2 × 10–5 C charge has an electric potential energy of 1.08 × 10–2 J. The electric potential, to the nearest whole number, is V.

Respuesta :

Answer:

150.

Explanation:

On edge

The electric potential, to the nearest whole number is 150 V.

What is the electric potential energy?

The electric potential energy denoted by U is proportional to the charge and inversely proportional to the distance between the point where its is brought from infinity to the charge.

U = kQ₁Q₂/r

For identical charge,

U =kQ²/r................(1)

and the electric potential is given by

V = kQ /r................(2)

Dividing both the equations, we get

U/V  = Q

Substitute charge Q =  7.2 × 10⁻⁵ C, Electric potential energy U = 1.08 × 10⁻² J, then the electric potential will be

V  = 1.08 × 10⁻² /   7.2 × 10⁻⁵

V = 150 Volts

Thus, the electric potential is 150 Volts.
