A particle is moved from `(0,0)`to `(a,a)` under a force `bar F = (3hati + 4hatj)` and path `2is OQP`.Let `W_(1) and W_(2)` be the work by done this force in these to paths .Then .

Options

A. `W_(1)=W_(2)`
B. `W_(1)=2W_(2)`
C. `W_(2)=2W_(1)`
D. `W_(2)=4W_(1)`

Answer

A

Explanation

(a) Given force is a constant force and work done by a constant force is always path independent.
`:. " " W_(1)=W_(2)`
