Most Important Selected Qs for JEE AdvancedPhysicsElectromagnetic Induction
A conducting rod PQ of length is dogged with a constant force F along two smooth parallel rails separated by a distance as shown in the adjacent figure. Then choose the correct statement(s).
Options
- Aterminal velocity of the rod, v_t= 2 F R B^2 ^2
- Bterminal velocity of the rod, v_t= F R B^2 ^2
- Cmaximum charge on the capacitor, q_ = F C R B
- Dmaximum charge on the capacitor, q_ = 2 F C R B
Correct answer
C. maximum charge on the capacitor, q_ = F C R B
Step-by-step solution
In steady state B V_ terminal = q_ C also iB = F & i = B v_ terminal R
