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.
