Vertical circular motion, Physics

Assignment Help:

The string of a pendulum is horizontal. Mass of the bob is m. Now the string is released, what is the tension in the string at lowest position
 
Ans) If string length is L,

 
 Conserving energy, velocity at lowest point is (2gL)1/2

 
Centripetal  force mv2/L

= 2mg.

 T- mg= mv2/L

T= 3mg
