Question

25. The velocity v of particle is given by v = At2 +Bt. what are dimension of A & B.​

Answer 1

Answer:The expression for velocity is given as V= ;

Now we know that the SI unit for velocity is m/s so to make both side equal both the sides should have m/s as their SI unit

So, if

                                       

                                       

Since si unit for time is second ‘t’ is replaced by s.

Similarly, Bt = m/s

                                        Bs=m/s
