An equilateral triangle of conducting wire of side 'a' is kept in a time (t) varying magnetic field B=B_0t, where B_0 is constant in such a way that the centre of field coincides with the centroid of the triangle. Now, choose the correct statement.

Answer»

INDUCED emf in the TRIANGLE will be `B_0a^2sqrt3`
Induced emf ACROSS any side of triangle will be `(B_0a^2)/sqrt3`
If a side passes through the centre, the induced emf across that side will REMAIN unchanged
If a side passes through the centre, the induced emf across other sides will increase.
