If B.E. of a satellite of mass 1000 kg is `10^(6)J`, then B.E. of another satellite of mass `10^(4)` kg, at the same height from the earth will be

Options

A. `10^(10)J`
B. `10^(7)J`
C. `10^(5)J`
D. `10^(2)J`

Answer

b

Explanation

`("B.E."_(1))/("B.E."_(2))=(m_(1))/(m_(2))=xx(r)/(r)=(10^(3))/(10^(4))" "therefore B.E._(2)=10^(7)J.`
