This is what I get

Explanation:

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

V_T=-(GM_1)/R_1-(GM_2)/R_2VT=GM1R1GM2R2

Rearranging and inserting given values

V_T=-G[(M_1)/R_1-(M_2)/R_2]VT=G[M1R1M2R2]
=>V_T=-6.67xx10^-11[(8000)/0.2+6000/0.15]VT=6.67×1011[80000.2+60000.15]
=>-5.34xx10^-6\ J
