Answer 1

a quantity has a value of

Answer 2

Correct Question :

• quantity has a value of -6m/s.It may be the a.speed and time b.velocity of a particle c.acceleration of a particle d.position of a particle

Required Solution :

• Given that a quantity has a value of - 6 m/s. We have to find if it can be any one of the given options.

•finding the dimension of Quantity

• →   Dimension =  Length / Time

• →   Dimension = LT⁻¹

• We know that, It can be the dimension of Speed as well as velocity.

• But Speed is a scalar quantity hence it can not be negative.

• So the following value is of Velocity because It is a vector quantity and its velocity can be both negative and positive.

• Hence, Option B is correct.
