The absolute potential at a distance of 2.0 m from a negative point charge is-100. v. what is the absolute potential 4.0 m away from the same point charge? a)-50. v b) -25. v c)-0.40 kv d)-020 kv e)-0.50 kv

The absolute potential 4.0 m away from the same point charge is -50 V.

(A) is correct option.

Explanation:

Given that,

Distance = 2.0 m

Potential = -100 V

Absolute potential = 4.0 m

We need to calculate the charge

Using formula of potential

Where, V = potential

q = charge

r = distance

Put the value into the formula

We need to calculate the potential

Using formula of potential

Hence, The absolute potential 4.0 m away from the same point charge is -50 V.
