Two heavy spheres of masses `10^(4)` kg and `10^(6)` kg and each of radius 20 cm are separated by a distance of 100 m. What will be the potential at the mid-point of the joining their centres ?

Text Solution

Verified by Experts


The total potential at A
`V=V_(P)+V_(Q)=-(Gm_(p))/(r )-(Gm_(Q))/(r )`
`therefore V=-(6.67xx10^(-11))/(50)[10^(4)+10^(6)]`
`therefore V=1.35xx10^(-6)J//kg`.
