Laws Of Motion Question 397

Question: If dimensions of velocity is bc1, acceleration bc2 and length ab, the dimensions of coefficient of friction are

Options:

A) a0b0c0

B) a1b0c0

C) a1b0c0

D) a1b1c0

Show Answer

Answer:

Correct Answer: B

Solution:

Here, we look for an equation involving velocity v, acceleration g and length r and coefficient of friction

μs . We arrive at

μs=tanθ=v2rg=b2c2bc2ab=a1b0c0
