A bob attached to the string oscillates back and forth resolve the forces acting on the bob in to compentswhat is theacceleration experience by the bob at an angle theta

Answer»

SOLUTION :
(i)Heretangentialforce(REF. Diagram )
F =mg sin `theta`
ma = mg` sin theta`
`:., a =G sin theta`
(II)CENTRIPETALFORCE
`F= T-mg sin theta`
`ma = T - mgsin theta`
`:. , a = (T -mgsin theta )/(m )`
