Question

26. A force F = 3i +2 j newton is applied on a body. If the displacement produced in the body is
x=4i+j metre, calculate the work done by the force.
​

Answer 1

Explanation:

f=3i+2j

x=4i+j

w=f.x

=(3i+2j)(4i+j)

=3(4)+2(1)

=12+2=14joule

Answer 2

Answer:

Explanation:

f=3i+2j

x=4i+j

w=f.x

=(3i+2j)(4i+j)

=3(4)+2(1)

=12+2=14joule
