Question

Two bodies of mass 10^2 kg and 10^4 kg are lying 1m apart. The gravitational potential at the mid-point
of the line joining them is:
(A) O
(B) -1.47 Joule/kg (C) 1.47 Joule/kg (D) -147 × 10^-9 joule/kg​

Answer 1

Answer:

d) -147 × 10^ -9 J/kg

Explanation:

Potential at center= Potential due to mass 1+ Potential due to mass 2

R1-R2= 0.5m

R1=R2= 0.5 = (-GM1/R1)-(GM2/R2)

= -6.67×10^-11[{10^2/5} +{10^3/5}]

= 1.47×10^-7 J/kg

= -147× 10^-9 J/kg.
