When a ceiling fan is switched on, it makes 10 rotations in the first 3 seconds. Assuming a uniform angular acceleration, how many rotation it will make in the next 3 seconds?

Text Solution

Verified by Experts

The correct Answer is:

`n_(1):n_(2):n_(3) . . .=1:3:5`: . . .
`therefore ` If `n_(1)=10` rotation then `n_(2)=30` rotation
