DimensionThe power of fundamental quantity involved in any physical quantity is called dimension of that physical quantity. The representation of physical quantity in terms of power of fundamental quantities involved in it is called dimensional formula of that physical quantity. Three fundamental quantities mass, length, and ...
The period of oscillation of a nonlinear oscillator depends on
the mass m, with dimensions of M; a restoring force constant k
with dimensions of M L-2 T-2and the amplitude A, with dimension of L. Then the period of
oscillation should be proportional to
A block rests on an inclined plane with coefficient of friction µ (which is dimensionless).
Let θ be the largest angle of inclination for which the block doesn’t slide down. Which
of the following is true?
The drag force F on a sphere moving slowly through a viscous fluid depends on the
viscosity of the fluid η (with units kg/(m s)), the radius R, and the speed v. Which of the
following quantities is F?
