A) \[(f'-f)n=\frac{1}{2}ff'{{m}^{2}}\]
B) \[\frac{1}{2}(f+f')m=ff'{{n}^{2}}\]
C) \[(f+f'){{m}^{2}}=ff'n\]
D) \[(f+f'){{m}^{2}}=ff'n\]
Correct Answer: A
Solution :
If u is initial velocity of any particle and a is a acceleration, then where, v is a speed of particle after t seconds. We have, ... (i) ...(ii) Now, ...(iii) ...(iv) ?(v) ?(vi) ?(vii) From Eq. (iii), ...(viii) So, from Eqs. (vii) and (viii),You need to login to perform this action.
