Question

. If the dimensions of a physical quantity are given
by MaLb TC, then the physical quantity will be
[AIPMT (Prelims)-2009]
(1) Velocity if a = 1, b = 0, C = -1
(2) Acceleration if a = 1, b = 1, C = -2
(3) Force if a = 0, b = -1, C = -2
(4) Pressure if a = 1, b = -1, C = -2​

Answer 1

Answer:

pressure =force/area

=MLT^-2/L^2=( M^1 L^-1 T^-2)

therefore a=1,b= -1, c= -2

si < br> choice (4) is correct
