NEET Physics Question - Gravitation

Assertion (A): Total energy is conserved in moving a satellite to higher orbit.

Reason (R): Sum of change in potential energy and kinetic energy is same in magnitude and opposite in nature.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Assertion (A) is false; moving a satellite to a higher orbit requires external work, increasing its total energy. Reason (R) is false in this context; \(\Delta K = -\Delta U\) applies only when mechanical energy is conserved, which is not the case when external work is done.
