Which of the following is not the unit of vectorquantity.
(a) m/s
(b) N
(c) M2
(d) A
Answers
Answer:
Speed
Explanation:
Speed is not a vector quantity. It has only magnitude and no direction and hence it is a scalar quantity
A) s2kgm2: This is S.I. unit for energy or work.
W=F⋅s
And we know work is a scalar quantity.
B) sN⋅m: This is S.I. unit for power.
P=F⋅v
And we know power is a scalar quantity.
C) Joule/sec is watt and we know watt is the S.I. unit for power that is same as sN⋅m
And power is a scalar quantity
D)Newton-sec is S.I. unit for linear momentum.
And we know Linear momentum is a scalar quantity which can be given as p=mv
So, we can conclude that only option D is satisfying the condition.
