lecture1|Class11|Physics|Dimension analysis

Today I am going to provide you the order of list of dimensions of quantities in which you require to remember it for purpose of different competition exam.






These notes are handwritten to improve your  experience if you like it and want more material on this topic then write on comment box..





A few important conversions:

i. Density:


1 kg/m3 = 10^-3 g/cm3 or


1 g/cm3 = 10^3 kg/m3


ii. Pressure:


1 N/m2 = 10 dyne/ cm2 or


1 dyne/cm2 = 0.1 N/m2.


.


iii. Coefficient of viscosity:


SI units is decapoise (N s/m2) and CGS
unit is poise.


1 poise = 10^-1 decapoise or


1 decapoise = 10 poise.


iv. Magnetic induction:


S I unit is tesla (Wb/m2) and CGS unit is
Gauss.


1 gauss = 10^-4 tesla or


1 tesla = 10^4 gauss.


v. Magnetic flux:


SI unit is weber and CGS unit is
maxwell.


1 Wb = 10^8 maxwell or


1 maxwell = 10^-8 Weber.
