An AC source is rated 220 V, 50 Hz. The average voltage is calculated in a time interval of 0.01 s. It
(a) must be zero
(b) may be zero
(c) is never zero
(d) is (220/√2) V

Here is your answer....,

Frequency - 50Hz.

Which means that the time period of the wave if 1/50 = 0.02 sec.

Here we are going to check the average voltage for the time interval of 0.01sec.

If the interval lies between π/2 to 3π/2. the average voltage will be zero. In all the other cases it will not be zero

So, the answer will be may be zero.

I hope it will help you and mark me as a brain list answer plz.
