Assertion : The direction of a zero (null) vector is indeteminate.
Reason : We can have `vecAxx vecB = vecA *vecB` with `vecA ne vec0 and vecB ne vec0`.

Options

A. (A) Statement 1 is true, statement 2 is true. Statement 2 is the correct explanation of statement 1
B. (B) Statement 1 is true, statement 2 is true. Statement 2 is not the correct explanation of statement 1
C. (C) Statement 1 is true and statement 2 is false.
D. (D) Statement 1 is false and statement 2 is true.

Answer

A

Explanation

Dimension formula of Boltzman constant
`k rarr [M^(1)L^(2)T^(-2)theta^(-1)]`
`(alpha[L^(1)])/([M^(1)L^(2)T^(-2)theta^(-1)][theta^(-1)])=M^(0)L^(0)T^(0)theta^(0)`
`alpha=[M^(1)L^(1)T^(-2)], beta=([M^(1)L^(1)T^(-2)])/([M^(1)L^(-1)T^(-2)])=[L^(2)]`
