A thin semi-circular conducting ring of radius R is falling with its plane verticle in horizontal magnetic induction `(vec B)`. At the position MNQ the speed of the ring is v, and the potential difference developed across the ring is A. (a) zeroB. (b) `BVpiR^(2)//2` and `M` is at higher potentialC. ( c) `piRBV` and `Q` is at higher potentialD. (d) `2RBV` and `Q` is at higher potential |
