In the arrangement shown, the pulleys are massless and frictionless. The rope connected to the block is also light and inexlensible. The system is in equilibrium. Select the correct alternative.

Options

A. The force on pulley `P_(1)` by the support is `mg (cos alpha - 1) hat(i) + mg sin alpha hat(j)`
B. The force on pulley `P_(1)` by the support is `mg (1 - cos alpha) hat(i) + mg sin alpha hat(j)`
C. The force on the support 3 by the string in `mg hat(i)`
D. The force on pulley `P_(2)` by the support in `mg (1 - sin alpha) hat(j) + mg cos alpha hat(i)`

Answer

B, C, D

Explanation

`Sigma f_(x) = 0`
