Question

12. A body executing uniform circular motion has at any instant its velocity vector and acceleration vector * 0/1 (a) Along the same direction (b) In opposite direction (c) Normal to each other (d) Not related to each other

Answer 1

A body executing uniform circular motion has has no relation between its velocity and acceleration vector at any instant

• In uniform circular motion the direction of velocity is not constant and it changes continuously
• As there is a change in the velocity there will be always an accelaration associated with it and the direction is not constant
• The direction of velocity vector and accelaration vector is not constant and changes from instant to instant
• Therefore option(D) is correct

Answer 2

Answer:

Option (D)
