A conducting rod of negligible resistance slides on a smooth U-shaped rail of resistance 1 Ω/m. At t=0 a magnetic field B=2t T is switched on. The rod is then moved left at constant speed 5 cm/s as shown. Select the correct statements.

Select all that apply

• Option A

  The current in the loop at t = 0 due to induced emf is 0.16 A, clockwise

• Option B

  At t = 2s, induced emf has magnitude 0.08 V

• Option C

  The magnitude of the force required to move the conducting rod at constant speed 5 cm/s at t = 2s, is equal to 0.08 N

• Option D

  The magnitude of the force required to move the conducting rod at constant speed 5 cm/s at t = 2s, is equal to 0.16 N
