A force \(\mathbf{F}=(2 \hat{\mathbf{i}}+4 \hat{\mathbf{j}}) \mathrm{N}\) is applied on an object of mass \(M\). What is the work done by this force in moving the object horizontally along the \(X\)-axis by \(3 \mathrm{~m}\) ?
- A \(2 \mathrm{~J}\)
- B \(4 \mathrm{~J}\)
- C \(6 \mathrm{~J}\)
- D \(8 \mathrm{~J}\)
Answer & Solution
Correct Answer
(C) \(6 \mathrm{~J}\)
Step-by-step Solution
Detailed explanation
Displacement of object is along \(X\)-axis by \(3 \mathrm{~m}\), \(\mathbf{x}=3 \hat{\mathbf{i} m}\) \(\text { Force }=2 \hat{\mathbf{i}}+4 \hat{\mathbf{j}} \mathrm{N}\) Work done by force,…
