A constant force F is being applied on a rod of length ‘l’  kept at rest on two parallel conducting rails connected at ends by resistance R in uniform magnetic field B  as shown. Which of the following statement is incorrect.
  • a)
    the rate of power delivered by the external force will be increasing continuously 
  • b)
    the rate of power delivered by external force will be decreasing continuously 
  • c)
    the power delivered by force will be increasing first and then will decreases 
  • d)
    the power delivered by force will be constant with time
Correct answer is option 'A,C,D'. Can you explain this answer?
Verified Answer
A constant forceFis being applied on a rod of length‘l’ ke...

as ‘a’  is decreasing continuously hence the rate of power delivered by external force will be decreasing continuously.
The correct answers are: the power delivered by force will be constant with time, the power delivered by force will be increasing first and then will decreases, the rate of power delivered by the external force will be increasing continuously
