In the solar system, the Sun is in the focus of the system for Sun-earth binding system. Then the binding energy for the system will be [given that radius of the earth's orbit round the Sun is `1.5 xx 10^(11) m` and mass of the earth `= 6 xx 10^(24) kg`]

Explanation

Binding energy of the system `= GM_(e) M_(s)//2r`
`= (6.6 xx 10^(-11) xx (6 xx 10^(24)) xx (2 xx 10^(30)))/((2 xx 1.6 xx 10^(11)))`
`= 2.6 xx 10^(33) J`
