If the length of the string was unchanged but the speed of the ball doubled, show mathematically how the inward force on the ball would change.

we know ac= $\frac{V^2}{r}$V2r and here r=L (L is the length of the string)
We know L1=L2=L and V2=2V1
ac1= $\frac{\left(V1\right)^2}{L}$(V1)2L
ac2= $\frac{\left(2V1\right)^2}{L}$(2V1)2L =4 ac1
F1=mac1 and F2=mac2 so F2=4F1
