A) the angular momentum remain constant
B) the linear momentum of particle remains constant
C) total mechanical energy remains constant in the absence of air resistance
D) all of the above
Correct Answer: C
Solution :
Since, torque due to weight of particle about point of projection is not zero so, angular momentum of system about the point of projection does not remains constant. But the particle moves under conservative force (weight of the particle). So, mechanical energy of system remains constant, hence is correct.
