In the diagram, q1 = +4.88*10^-8 C. What is the potential difference when
you go from point A to point B?
Include the correct sign, + or - .

0.538 m
1.36 m

(Hint: Does V go up or down when you go
from B to A?) (Unit = V)

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,

ΔV = 1139.3 V = 1.139 KV (+ve sign shows V goes up)
