Physics Question on Force and Mass

A uniform force of (3i^+j^)(3\hat{i}+\hat{j}) newton acts on a particle of mass 2 kg. Hence the particle is displaced from position (2i^+k^)(2\hat{i}+\hat{k}) metre to position (4i^+3j^−k^)(4\hat{i}+3\hat{j}-\hat{k}) metre. The work done by the force on the particle is

A

9J^ 9\hat{J}

B

6J^6\hat{J}

C

13J^13 \hat{J}

D

13J^13 \hat{J}

Answer

9J^ 9\hat{J}

Explanation

Solution

The correct option is (A): 9J^ 9\hat{J}
