Can u pls solve 56th question

Dear Student,

W e k n o w, P = \frac{w o r k d o n e}{t i m e} = \frac{f o r c e \times d i s p l a c e m e n t}{t i m e} = f o r c e \times \frac{d i s p l a c e m e n t}{t i m e} = f \times v f = \frac{P}{v} f \propto \frac{1}{v} [A s p o w e r i s c o n s \tan t]

Regards,
