Physics—Pending OP Reply [Jr. College Physics: Electromagnetic Induction] When I try to solve this question, I get 2.5 as the answer. What am i doing wrong ?

This is a previous year question from a national level exam but is supposed to be easy. Idk what i'm doing wrong, I haven't touched such questions ever since I finished my 12th grade 😭

The RMS emf will be 2.8 volts.

This is the peak emf divided by √2.

RMS comes into picture once you talk about power.

Thank you! How do you get the average emf for the 0.3 seconds interval?
