A) \[\vec{T}.\vec{v}\]
B) kinetic energy
C) Gravitational potential energy
D) \[\vec{T}\times \vec{v}\]
Correct Answer: A
Solution :
[a] The tension vector \[\overrightarrow{T}\]is always normal to velocity vector. Hence \[\overrightarrow{T}.\vec{V}\]is always zero. \[\Rightarrow \](1) is correct choice.You need to login to perform this action.
