Question

A body is displaced by 20m, when a force of 20 N acts on the body. The work done is
a) 20 J
b) 200 J
c) 400 J
d) 40 J​

Answer 1

Answer:

given,

s=20m

f=20N

therefore

work done =f×s

work done = 20×20=400joules

Answer 2

$\huge{\mathfrak{\purple{Question}}}$

A body is displaced by 20m, when a force of 20 N acts on the body. The work done is

a) 20 J

b) 200 J

c) 400 J

d) 40 J

$\huge{\mathfrak{\purple{Answer}}}$

c.) 400J

$\huge{\mathfrak{\purple{Explanation}}}$

work done = F * s

where F is the force applied and s is the displacement produce by this force .

so work done W = 20 * 20 = 400 Joule.
