Question

A sleeve of mass 2 kg at origin can move on wire of parabolic
shape x2 = 4y. Two forces F, = 6N and F, = 8N are applied on
the sleeve. F, is constant and is in x-direction. F, is constant in
direction and magnitude. Body is displaced from origin to x = 4
then net work done by F, and F, is :-

Answer 1

Answer:

w1=24J and w2=32J

Explanation:

work done =force×displacement in direction of force

so

6N force is in x direction and displace in x direction is 4 so

w1=6×4 =24J

and same for 8N force

w2=8×4=32J

same
