Question

A body of mass 5kg is placed at the origin, and can
move only on the x-axis. A force of 10N is acting on
it in a direction making an angle of 60° with the x-
axis and displaces it along the x-axis by 4m. The
work done by the weight is.
O A:
2.5 J
ов:
7.25 J
D
zero​

Answer 1

Answer:

Angle between force and displacement θ=60

o

Given : F=10 N S=4 m

Work done W=FScosθ

⟹W=10×4×cos60=20 J

Answer 2
