A) work done by the force is \[3J\]
B) work done by the force is \[-45\text{ }J\]
C) at (0, 0) speed of the particle must be zero
D) at (0, 0) speed of the particle must not be zero
Correct Answer: B
Solution :
Work done of the particle \[W=F.ds\] \[=(7\hat{i}-6\hat{i}).(3\hat{i}+4\hat{j})=-21-24\] \[W=-45J\]You need to login to perform this action.
