  • Ruby negi thankyou
    option c is correct... remember there is difference between rest Mass and relativistic mass.. in relativity, f=ma violates...

    when it is not clearly mention that m is relativistic mass always try to take m relativistic mass and mo rest Mass...

    see full calculation.. I hope it's helpful for you
  • Abhishek singh thankyou
    I have derived the formula for you. I used formula of relativistic momentum and derived it with respect to time. Best regards.

    you got stuck in differentiation. do it again by yourself. I have used quotient formula for differentiation.

    this will also help you. because newtons second law is rate of change of momentum. and in momentum due to relativity we multiply by gamma factor. so the output that comes i attache...
