Question

60. In position A kinetic energy of a particle is 60 J and
potential energy is - 20 J. In position B, kinetic
energy is 100 J and potential energy is 40 J. Then, in
moving the particle from A to B
(a) work done by conservative forces is 50 J
(b) work done by external forces is 40 J
(c) net work done by all the forces is 40 J
(d) net work done by all the forces is 100 J​

Answer 1
