Question

A cloud carries a charge of 1000C at a potential of 5 kV. If the cloud discharge, the amount of energy released:

• A. $5\times {10}^{6}J$
• B. $2.5\times {10}^{6}J$
• C. ${10}^{7}J$
• D. $5\times {10}^{3}J$

Answer 1

The correct option is A $5\times {10}^{6}J$

Work done to more charge $=q.\Delta v$
$\therefore$ Energy released when cloud is discharged$=1000\times 5\times {10}^3$
$=5\times {10}^6$ J
