What will be the potential energy of a body of mass 67 kg at a distance of `6.6 xx 10^(10)` m from the centre of the earth? Find gravitational potential at the earth? Find gravitational potential at this distance?

Explanation

Mass of the earth `M = 6.0 xx 10^(24) kg , m = 67 kg`
`G= 6.67 xx 10^(-11) Nm^(-2) kg^(-2)`
Gravitaional potential `V = -(GM)/(R)`
`= (6.67 xx 10^(-11) xx 6 xx 10^(24))/(6.6 xx 10^(10))`
`V = -6.1 xx 10^(3) JKg^(-1)`
