Statement 1: Assertion : A vector can have zero magnitude if one of its rectangular components is not zero.
Statement 2: Reason : Scalar product of two vectors cannot be a negative quantity.

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

B, C

Explanation

`F=(1)/(4pi in_(0))(q_(1)q_(2))/r^(2) rArr MLT^(-2)=[1/in_(0)](A^(2)T^(2))/L^(2)`
`rArr [1/in_(0)]=M^(1)L^(3)A^(-2)T^(-4) rArr [in_(0)]=M^(-1)L^(-3)A^(+2)T^(4)`
`F/L=mu_(0)/(4pi)(i_(1)i_(2))/(r)`
`[ML^(-2)]=[(mu_(0)A^(2))/L]rArr [mu_(0)]=MLA^(-2)T^(-2)`
