A particle moves from \((1,0,3)\) to the point \((-3,4,5)\), when a force \(\mathbf{F}=\hat{\mathbf{i}}+5 \hat{\mathbf{k}}\) acts on it. Amount of work done in joules is
- A 14
- B 10
- C 6
- D 15
Answer & Solution
Correct Answer
(C) 6
Step-by-step Solution
Detailed explanation
Starting point of particle \(=\hat{i}+3 \hat{k}\) \[ \begin{aligned} \text { Ending point of particle } & =-3 \hat{i}+4 \hat{j}+5 \hat{k} \\ \text { force }(F) & =\hat{i}+5 \hat{k} \end{aligned} \] \(\therefore\) Displacement of the particle…
