question 117

Multiple Choice

A particle located at the position vector $\hat { \mathbf { r } } = ( \tilde { \mathbf { i } } + \hat { \mathbf { j } } )$ m has a force $\overrightarrow { \mathbf { F } } = ( 2 \hat { \mathbf { i } } + 3 \tilde { \mathbf { j } } )$ N acting on it.The torque about the origin is

• A)(1 )N.m
• B)(5 )N.m
• C)(-1 )N.m
• D)(-5 )N.m
• E)(2 \(\hat { \mathbf { i } }\) + 3 \(\hat { \mathbf {j} }\) )N.m
