Question #ca63a

Answer 1

`975muJ`

Explanation:

Electric potential is by definiton electric potential energy per unit charge, i.e., how much potential energy a unit of charge has.

`V= U/q rArr U= qV`

where q is the charge, U potential energy, and V potential.

Hence a change in potentials (`Delta V`) results in change of potential energy(`Delta U`):

`rArr DeltaU = qDeltaV = 6.5 muC*150V = 975 muC*V=975muJ`

Note: A voltage 150 V is applied means the potential difference between the plus and minus terminals is 150V.
