Answer:
ΔV = 1139.3 V = 1.139 KV (+ve sign shows V goes up)
Explanation:
The potential difference while moving from point A to Point B is given as follows:
where,
ΔV = potential difference from A to B = ?
= Potential at point A =
= Potential at point B =
Therefore,
where,
k = Colomb's Constant = 9 x 10⁹ N.m²/C²
q = magnitude of charge = 4.88 x 10⁻⁸ C
= distance of point A from charge = 1.36 m
= distance of point B from charge = 0.538 m
Therefore,
<u>ΔV = 1139.3 V = 1.139 KV (+ve sign shows V goes up)</u>
