Physics, asked by jaskirat65, 1 year ago

if both the speed of a body and radius of the circular path are doubled what will happen to centripetal force

Answers

Answered by ArnimZola

Let the mass of the body be m

Let the radius be r and velocity be v

Hence, the centripetal force = $\frac{mv^2}{r}$

Now, the velocity is doubled. Hence, the velocity becomes 2v

And radius is also doubled = 2r

Hence, the new centripetal force = $\frac{m(2v)^2}{2r}$

New centripetal force = $\frac{4m(v)^2}{2r}$

Hence, the centripetal force becomes two times.

jaskirat65: are you sure this answer is right

jaskirat65: i think you have to double the radius also

ArnimZola: Yes, Let me edit it

ArnimZola: Done

jaskirat65: m4v^2/2r= m2v^2/r

jaskirat65: i think this is right answer

ArnimZola: yes, i have edited it

jaskirat65: ok
