If m varies directly as p, and m=63 when p=9, m when p =5 is 35.
When a physical quantity m is directly proportional another quantity p.
m α p
m =kp
Given m=63 when p=9, plug the values, we get
63 = k x 9
k = 7
Using the same expression again for p = 5, we get
m = 7 x 5
m = 35
Thus, the value for m when p = 5, is 35.
