Answer:
5.0 × 10⁴ J
Explanation:
Given :
Force = 50 N
Distance = 1 kilometers = 1000 m
We are asked to find work done.
We know :
Work done = Force × Distance
i.e. W = F × d
W = 50 × 1000 J
W = 50000 J
W = 5.0 × 10⁴ J
Therefore , required work done is 50 N.

ANSWER:
50, 000 J
EXPLANATION:
Work = force × displacement
W = Fd
Given:
F = 50 N
d = 1 km
J = Nm, so convert 1km into m
1 km = 1, 000 m
W = ( 50 N) ( 1000 m)
W = 50, 000 N.m
W = 50, 000 J
