A) BvR and non-zero
B) 2BvR and zero
C) 4BvR and non-zero
D) 4BvR and zero
Correct Answer: C
Solution :
(c) 4BvR and non-zero The potential difference between B and d will be \[{{V}_{d}}-{{V}_{b}}=Bv\times 4R\] \[{{V}_{d}}-{{V}_{b}}=4BvR\] The current in the loop will be zero because we know that net emf in any closed loop is zero.
