The answer is 4.8 mV, but I keep getting 2.7

I used E = NABwsin(wt)

Because we have no coil, we can take out N so that leave sus with BAwsin(wt)

What am I doing wrong?

THank you

A=a²=0.04 m²,

ωt=20º

E=- dΦ/dt = - d(B•A•cos(ωt))/dt =

= B•A• ω•sin(ωt) =

=2•0.04• (π/18) •sin20º = 4.775•10^-3 V ≈4.8 mV
