If the dimensions of a physical quantity are given by , then the physical quantity will be
Multiple Choice Options
- A velocity if a = 1, b = 0, c = -1
- B acceleration if a = 1, b = 1, c = -2
- C force if a = 0, b = -1, c = -2
- D pressure if a = 1, b = -1, c = -2
Step-by-Step Verified Solution
Velocity = [LT -1 ] so a = 0, b = 1, c = -1
Acceleration = [LT -2 ] so a = 0, b = 1, c = -2
Force = [MLT -2 ] so a = 1, b = 1, c = -2
Pressure = f o r c e A r e a = [ M L T _ 2 ] [ L 2 ] = [ M L _ 1 T _ 2 ] ,
so a = 1, b = - 1, c = - 2
