Question

4. A particle is acted upon by a conservative force F = (1 +6j) N (no other force is acting on the particle). Under the
influence of this force particle moves from (0,0) to (-3m, 4m), then
(a) work done by the force is 3 J
(b) work done by the force is -45 J
(c) at (0,0) speed of the particle must be zero
(d) at (0,0) speed of the particle must not be zero​
