The acceleration of a particle at any instant has two components, radial component and tangential component. These two components will be
(a) parallel to each other
(b) perpendicular to each other
(c) inclined at 45^0
(d) opposite to each other
This question was addressed to me in class test.
I'd like to ask this question from Linear Acceleration topic in portion Kinematics & Kinetics of Motion of Machine Kinematics
