A particle is moving in a vertical circle. The tensions the string when passing through two positions at angles 300 and 600 from vertical (lowest positions) are T1 and T2 respectively. Then:
Correct answer: D. Tension in the string always remains the same.
- A. T1 = T2
- B. T2 > T1
- C. T1 > T2
- D. Tension in the string always remains the same.
Explanation
It depends on the centripetal force needed to keep the particle in circular motion and the weight component along the string, both of which do not change throughout the circular motion.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
