Answer:

A. is double OK branlistb please

Answer 2

Correct answer A.) Doubled

Centripetal acceleration is given by a=v 2/R. Hence, if v is doubled and R is halved, we get a ′=4v 2 /(R/2)=8a

What happens to centripetal force if speed is doubled?

Note that the centripetal force is proportional to the square of the velocity, implying that a doubling of speed will require four times the centripetal force to keep the motion in a circle. ...

Answer above is correct
