If $W_1, W_2$ and $W_3$ represent the work done in moving a particle from $A$ to $B$ along three different paths $1, 2$ and $3$ respectively (as shown) in the gravitational field of a point mass $m$,find the correct relation between $W_1, W_2$ and $W_3$.

  • A
    $W_1 > W_2 > W_3$
  • B
    $W_1 = W_2 = W_3$
  • C
    $W_1 < W_2 < W_3$
  • D
    $W_2 > W_1 > W_3$
