NEET Physics Question (2024) — Solution

Question

A force defined by F= t^2+ t acts on a particle at a given time t. The factor which is dimensionless, if and are constants, is:

Options

  1. A. t /
  2. B. t
  3. C. / t
  4. D. t /

Answer

A. t /

Step-by-step solution

From principle of homogeneity aligned & [F]= [ t^2 ]=[ t] \\ & [ ]= [F] [t^2 ] and [ ]= [F] [t] \\ & [ ][t]=[ ] \\ & t = dimensionless aligned
