Question

A body of mass m = 2 kg is projected with speed
u = 20 m/s at an angle 60° with the horizontal from
the surface of earth. Torque of its weight about the
point of projection at t = 2 s is (take g = 10 m/s2)
(1) 200 Nm
(2) 200 root 3 Nm
(3) 400 root 3 Nm
(4) 400 Nm​

Answer 1

Answer :-

x = 10 × t

= 10 × 2

= 20 m

T = mg x

= 2 × 10 × 20

= 20 × 20

= 400 N
