Units And Measurement

From Coulomb's law two stationary point charges and attract or repel each other with a force which is directly proportional to the product of the charges and inversely proportional to the square of distance between them, i.e., (if Hence, units of

Pascal is unit of pressure. Pascal is unit of pressure, hence its dimensional formula is ] Dimensional formula of Pascal-second is From the formula of coefficient of viscosity, we have where is force, is area and is velocity gradient. Dimensions of Hence, Pascal-second has dimensions of coefficient of viscosity.

Volume of sphere (V) = % error m volume = =
