Q. Which quantity has the dimension ML²T⁻²?

किस मात्रा का आयाम ML²T⁻² है?

Torque
टॉर्कः

Work
काम

Both A and B
ए और बी दोनों

Power
शक्ति

Work (W): Work is defined as Force

\times

Distance. The dimensions of Force are

M L T^{- 2}

and Distance is

L

. So,

W = (M L T^{- 2}) (L) = M L^{2} T^{- 2}

Torque (Ï): Torque is defined as Force

\times

Perpendicular distance from the axis of rotation. The dimensions of Force are

M L T^{- 2}

and Distance is

L

. So,

τ = (M L T^{- 2}) (L) = M L^{2} T^{- 2}

Both work and torque have the same dimensional formula, although they represent different physical quantities.
