Physics And Measurement Question 250

Question: Write the dimensions of a×b in the relation E=bx2at where E is the energy, x is the displacement and t is time

Options:

A) ML2T

B) M1L2T1

C) ML2T2

D) MLT2

Show Answer

Answer:

Correct Answer: B

Solution:

[b] Here, b and x2=L2 have same dimensions Also, a=x2E×t=L2(ML2T2)T=M1T1
