A cycle wheel with 64 spokes is rotating...

A cycle wheel with `64` spokes is rotating with `N` rotations per second at right angles to horizontal component of magnetic field. The induced `e.m.f` generated between its axle and rim is `E`. If the number of spokes is reduced to `32` then the value of induced e.m.f. will be
