In non-uniform circular motion, the net acceleration of the particle is directed:
A. Strictly towards the center
B. At an angle to both the radius and the tangent
C. Strictly along the tangent to the circle
D. Outwards, away from the center
Answer: Option B
Solution (By JKExamLibrary)
In non-uniform circular motion, the speed of the particle changes. This requires a tangential acceleration (at) to change the speed, and a centripetal/radial acceleration (ac) to change the direction. The net acceleration is the vector sum of these two mutually perpendicular components, so it points inward at an angle to the radius.
