A particle moved from position `vec r_(1) = 3 hati + 2 hatj - 6 hatk `to position`vecr_(2) = 14 hati + 13 hatj +9 hatk` undre the action of a force `(4 hati + hatj +3 hatk)` newtons . Find the work done .

A

`10J`

B

`100 J`

C

`0.01 J`

D

`1J`

Text Solution

Verified by Experts

The correct Answer is:
