Binding energy of a revolving satellite at height ' $h$ ' is $3.5 \times 1 0^{8} J$ . Its potential energy is

Options:

Answer:

Solution:

Concept: Binding energy $= +$ (work done to assemble the planet plus satellite system) $∴ BE = + W$ We know, potential energy change is related as: $U = (- W)$ So the potential energy of the system is $U = - (\frac{GM _{m}}{r + h}) = - W = - 3.5 \times 1 0^{8} J$
