Question

If given arrangement is moving towards left with speed v then potential difference between B and D and current in the loop are respectively answer is 4BvR and zero plz explain how

Answer 1

Answer:

In the given situation following are the steps which can be seen for better understanding,

Step 1:

Look at the given data,

Fact 1: arrangement is moving towards left

Fact 2: speed is V

Question is to find the difference between B and D and current in the loop.

Step 2:

Understand that the Curve wire moving transnational can be equalize by straight wire jointed to its free end.

Step 3:

Because of step 2, the potential difference between B and D will be =

Vd - Vb = BV * 4R

             = 4BVR

Step 4: Thus making the current in the loop zero.

How?

Since the net emf in any closed loop is supposed to be zero.

Answer 2

Explanation:

potential energy between B and D

Vd-Vb = BV×4R

= 4BVR

current is zero as the net emf in closed loop is zero.

Answer 4BVR and Zero
