Question

a force (3i+2j)N displaces an object through a distance (2i-3j)m.
the workdone is???
a - 0 J
b - 5 J
c - 12 J
d - 13 J

Answer 1

Answer:

Work done, W = 0 J

Explanation:

It is given that,

Force, F = (3i + 2j)

Distance, d = (2i - 3j)

We have to find the work done by an object. It is given by the product of force and distance i.e.

$W=F.d$

$W=(3i+2j).(2i-3j)$

W = 6 - 6 = 0 Joules

Hence, the work done is 0 J i.e. no work is done by the object.
