Question

A particle moves in the x-y plane under the action of a force F such that the value of its liner
momentum () at anytime t is Px=2 cost, Py= 2sin t. The angle 8 between F and p at a given
time t. will be
(1) 0 = 0°
(2) 0 = 30°
(3) 0 = 90°
(4) 0 = 180°​

Answer 1

Explanation:

A particle moves in the x-y plane under the action of a force F such that the value of its liner

momentum () at anytime t is Px=2 cost, Py= 2sin t. The angle 8 between F and p at a given

time t. will be

(1) 0 = 0°

(2) 0 = 30°

(3) 0 = 90°

(4) 0 = 180°
