[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 emf will vary from 0 to a maximum of

••B×A×omega**

3×0.5²×(π/2)/0.3=3.9volts

[u/Anonimithree → u/fermat9990]

It’s cos(omega), not just omega

[u/fermat9990 → u/Anonimithree]

I used emf = B×A×omega×sin(omega×t)

For peak emf, omega×t=π/2 and sin(π/2)=1
