Question

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

Answer 1

generally force=mass*acceleration
and
centripetal acceleration \[a=\frac{ v^2 }{ r }\]
so
\[force=m*a=m*\frac{ v^2 }{ r }\]
now can u do it? @Shaekitchen

Answer 2

can u make out any relationship between force and mass?

Answer 3

well
according to the above equation
force is proportional to the mass
so
if u double the mass then u have to double the force also :)
