Question

A particle moves in X-Y plane under the action of forces F such that the values of linear momentum p at any times is px​=2cost and py​=2sint. The angle between F and p​ at the time t will be:

(A) θ = 0°
(B) θ = 30°
(C) θ = 90°
(D) θ = 180°​

Answer 1

Answer:

A particle moves in the X-Y plane under the action of forces F such that the values of linear momentum p at any time is px=2cost and py=2sint. The angle between →F and →p at the time t will be. A. 0o.
