Rearrange the formula C = 2mr for r.

Question

M

A r = 2mc

M

B r = C/(2x)

M

C r = (2C)/r

D r = (2a)/c

Answer 1

To rearrange the formula C = 2mr for r, we need to isolate r on one side of the equation.

C = 2mr
Divide both sides by 2m:
C/(2m) = r

So, the rearranged formula for r is:
B) r = C/(2m)
