125 rain drops are combined to from a single drop . The ratio of the total energy of 125 drops to that of a single drop is

A

2

B

5

C

10

D

`5/2`

Text Solution

Verified by Experts

The correct Answer is:
B
`(125)4/3 pir^(3)=4/3piR^(3)=4/3piR^(3) " " :. R = 5r or r/R = 1/5`
`:. (S_(1))/(S_(2)) = 125 (r/R)^(2)=125 xx1/25 =5`
