Which of the following pairs does not have similar dimensions? [2001]

The dimensions of universal gravitational constant are [2000]

In an experiment, the percentage of error occurred in the measurement of physical quantities A, B, C and D are 1%. 2%, 3% and 4% respectively. Then the maximum percentage of error in the measurement X, where X = (A ^ 2 * B ^ (1/2))/(C ^ (1/3) * D ^ 3) will be[2019]

A physical quantity of the dimensions of length that can be formed out of c, G and e^2/4πεo is (c is velocity of light, Gis universal constant of gravitation and e is charge] [2017]

A physical quantity A is related to four observations a, b, c and das follows, A = a^2b^3 / c√d The percentage errors of measurement in a, b, c, and d are 1%, 3%, 2% and 2% respectively. What is the percentage error in the quantity A [2013]

Planck’s constant (h), speed of light in vacuum (c) and Newton’s gravitational constant (G) are three fundamental constants. Which of the following combinations of these has dimension of length [2016]

If energy (E), velocity (V) and time (T) are chosen as the fundamental quantities, the dimensional formula of surface tension will be [2015]

If dimensions of critical velocity vc of a liquid flowing through a tube are expressed as [η^xρ^yr^z], where η, ρ and r are the coefficient of viscosity of liquid, density of liquid and radius of the tube respectively, then values of x, y and z are given by [2015]

You measure two quantities as A = 1.0 m±0.2m B = 2.0m±0.2m we should report correct value for √AB as

Measure of two quantities along with the precision of respective measuring instrument is A = 2.5ms¯¹ ±0.5ms-1, B=0.10s±0.01s The value of AB will be
