A particle is displaced from position `vecr_1 = (3hati + 3hatj + 6hatk)` to another position `vecr_2 = (14hati + 13hatj + 9hatk)` under the impact of a force `5hati N`. The work done will be given by

A

55 J

B

65 J

C

45 J

D

75 J

Text Solution

Verified by Experts

The correct Answer is:
A
Work done = Force `xx` Displacement
`= (hat5) . (hat11 + hat11 + hat15) = 55J`
