SamplePhysics· MCQ+4 / -1

XPQY is a vertical smooth long loop having a total resistance

R

where PX is parallel to QY and separation between them is

ℓ

. A constant magnetic field

B

perpendicular to the plane of the loop exists in the entire space. A rod CD of length

L

(

L > ℓ

) and mass

m

is made to slide down from rest under the gravity as shown in figure. The terminal speed acquired by the rod, in

m/s

(

g =

acceleration due to gravity), is:

A rectangular vertical loop with corners P and Q at the top and X and Y at the bottom. A resistor R sits in the top arm PQ. PX and QY are the vertical side rails, separated by a distance l. A horizontal rod CD of length L, greater than l, lies across the rails and slides downward under gravity, indicated by a downward arrow.

A. $\frac{2 m g R}{B ^{2} ℓ ^{2}}$
B. $\frac{8 m g R}{B ^{2} ℓ ^{2}}$
C. $\frac{2 m g R}{B ^{2} L ^{2}}$
D. $\frac{m g R}{B ^{2} ℓ ^{2}}$
