What is the expression of the centripetal force required for a uniform circular motion?

agent0smith · Answer

That expression is only centripetal acceleration. Net force = ma

mtalhahassan2 · Answer

but don't be used that equation for centripetal acceleration which I mention

agent0smith · Answer

The question is asking about force when the mass doubles, not acceleration.

mtalhahassan2 · Answer

oh

mtalhahassan2 · Answer

so.....mass doubles ---------> acceleration is unchanged, as long as the force which causes such an acceleration is able to be as large as necessary (e.g. the inextensible string holding it in circular motion didn't rupture).

agent0smith · Answer

So what happens to the force, when the mass doubles, and acceleration is unchanged?

mtalhahassan2 · Answer

The larger the mass, the larger the centripetal force be agree

mtalhahassan2 · Answer

are you agree with that?

agent0smith · Answer

Of course. But you haven't answered my question.

mtalhahassan2 · Answer

I am not sure but is the force be 0?

agent0smith · Answer

No... That makes no sense at all.

The larger the mass, the larger the centripetal force be 

How would the force becoming LARGER... then suddenly become zero...

mtalhahassan2 · Answer

lol yea so the force be double

mtalhahassan2 · Answer

so....If you double the mass, you will have to double  the centripetal force to keep it travelling in the same circular path at the same velocity.

agent0smith · Answer

Exactly.

@agent0smith thanks man I am stupid

lol you're welcome.
