A heavy particle is projected with a velocity at an angle with the horizontal into the uniform gravitational field. The slope of the trajectory of the particle varies as

Options

A. remains constant
B. increases
C. decreases
D. initially decreases and after its highest point increases

Answer

B

Explanation

Torque, `tau_(0)=mg xx r_(bot)` As, `r_(bot)` is continuously increasing or torque is continuously increasing on the particle. Hence, angular momentum is continuously increasing
