This is what I get

Explanation:

We know that The gravitational potential is the gravitational potential energy per unit mass.
Gravitation potential at point #P# is equal to the sum of gravitational potentials between two masses and unit mass at #P# respectively.

#V_T=-(GM_1)/R_1-(GM_2)/R_2#

Rearranging and inserting given values

#V_T=-G[(M_1)/R_1-(M_2)/R_2]#
#=>V_T=-6.67xx10^-11[(8000)/0.2+6000/0.15]#
#=>-5.34xx10^-6\ J#
