A) 6 N
B) 4 N
C) 2 N
D) 1 N
Correct Answer: C
Solution :
Motional emf \[e=Bvl\Rightarrow e=2\times 2\times 1=4\ V\] This acts as a cell of emf \[E=4\ V\]and internal resistance \[r=2\Omega \]. This simple circuit can be drawn as follows Current through the connector \[i=\frac{4}{2+2}=1\ A\] \magnetic force on connector\[{{F}_{m}}=Bil=2\times 1\times 1=2\ N\] (Towards left)You need to login to perform this action.
