Correct Answer - Option 1 : 7.5 MJ
Concept:
Electric field: The space or region around the electric charge in which electrostatic force can be experienced by other charged particles is called an electric field by that charge.
Electric potential difference: The amount of work done to move a unit charge from a point to another point in a space where an electric field is present is called an electric potential difference.
\({\rm{Potential\;difference}}\left( {\rm{V}} \right) = {\rm{\;}}\frac{{Work\;done\left( W \right)}}{{Charge\left( Q \right)}}\)
Work done (W) = Energy gained = Q V
Calculation:
Given:
Q = 100 kC = 105 C, V = 75 V
W = QV
W = 105 × 75
W = 75 × 105
W = 7.5 MJ
