you have to draw a function w.r.t to the distance from the center , integrate it up to the distance till the charge distribution is mentioned along its area or volume whatever charge density is given , result would be the total charge contained by that object and you can use gauss theorem after...

yeah in that case : Tcosθ = mg and , Tsinθ= mv(square)/r

And one more thing , so I can conclude , there is no vertical uniform circular motion theoretically as well. But horizontally it would be possible right?

@thank you nasu , i got the point . thank you everyone .

If it is a uniform circular motion , then there won't be any tangential acceleration throughout the motion , I'm talking theoretically not practically , I know there is no motion as uniform circular motion but still my doubt persist. Weight at other position counter balance tension or provide...

Side.

Tension would be equal to centripetal force and acceleration is towards the center v sqaure divided by radius of circle . See everything is defined except weight component.

@Nugatory , I understand there should be some net force but that force is centripetal force acting towards center not the weight , weight has to be balanced as it has no tangential acceleration. My main concern is at a particular point that is when string is horizontal weight simply acts...

not in equilibrium but forces should be balanced as it is a case of uniform circular motion no tangential acceleration only centripetal . [Mentor's note: This post has been edited to remove some unnecessary personal argumentation]

it has to be , otherwise system won't be working as it does . There is no counter force to balance it. a system is in equilibrium has all ∑force = 0 .

Hi , just curious about the F.B.D of a pebble moving in a vertical circle, which component that balances the weight of the pebble at the horizontal position , as tension is providing the required centripetal force , weight is acting downwards , which component balances it ?
