List of top Physics Questions on Units and measurement asked in TS EAMCET

The force \(F\) acting on a particle in terms of its distance \(x\) from a fixed point is given by \[ F=\frac{A}{B+x^{1.5}}. \] If the dimensional formula of \(AB\) is \[ [M^aL^bT^c], \] then the value of \(a+b+c\) is

Statement-I: When two quantities are multiplied, the relative error in the result is the sum of the relative errors in the quantities.
Statement-II: When two quantities are divided, the relative error in the result is the difference of the relative errors in the quantities.

If the errors in the measurements of diameter, length and electrical resistance of a wire are 1%, 0.5% and 2% respectively, then percentage error in the determination of the resistivity of material of the wire is:

If A, B and C are three different physical quantities with different dimensional formulae, then the combination which can never give a proper physical quantity is

The error in the measurement of force acting normally on a square plate is 3%. If the error in the measurement of the side of the plate is 1%, then the error in the determination of the pressure acting on the plate is

In an experiment, the coefficient of viscosity (in mPa s) of a liquid was determined as 2.62, 2.68, 2.58, 2.57, 2.54 and 2.55. The mean absolute error in the determination of the coefficient of viscosity of the liquid is

A piece of length 3.532 m is cut from a rod of length 43.4 m. The length of the remaining rod in metre is (up to correct significant figures)

If the length of a rod is measured as 830600 mm, then the number of significant figures in the measurement is
