The magnetic flux throug a coil perpendicular to the plane is given by `phi=5t^(3)+4t^(2)+2t` calculate the induced emf through the coil at t =2S.

Text Solution

Verified by Experts

Given :
We know that `e=-(dphi)/(dt)`
`e=(d)/(dt)(5t^(3)+4t^(2)+2t)`
`e=15t^(2)+8t+2`
for t = 2s, e=15xx(2)^(2)+8(2)+2`
e = 78V
