Question

What is the type of measure for force?
A. Amp
B. Seconds
C. Newton
D. Erg

Answer 1

Hint: The International System of Units is given as the internationally accepted form of the metric system. It is basically a system of measurement with an official acceptance in almost every country in the world. The unit of force is also given in this unit system. The unit is not according to the dimensional relation. Thus the obtained unit is named as a common term which is the name of a popular scientist in the world.

Complete answer:
The ampere is sometimes abbreviated as amp, is the base unit of the electric current in the International System of Units. The seconds is abbreviated as s or sec is defined as the standard international unit (SI) for time. Erg is the unit of energy or the work done in the centimetre-gram-second system of physical units prevailing in physics. As we all know, internationally, many prefer to use a single system referred to as the SI unit for measuring force. The SI unit which is used for measurement of force is given as Newton.
The S.I unit of force can be written as,
$\begin{align}
  & F=\left( Kg \right).\left( m{{s}^{-2}} \right) \\
 & \Rightarrow F=Kgm{{s}^{-2}} \\
\end{align}$
This can be termed as newton.

So, the correct answer is “Option c”.

Note:
The S.I system describes the ampere in terms of some other base units by calculating the electromagnetic force between electrical conductors carrying electric current. One second is defined as the time that passes during $9.19263\times {{10}^{9}}cycles$ of the radiation created by the transition between two levels of the $caesium\text{ }133$ atom. There are also some other expressions for the second. In order to lift a pound weight one foot requires $1.356\times {{10}^{7}}ergs$. It is equivalent to the work done by a force of one dyne that is experienced through a distance of one centimetre. This is equal to ${{10}^{-7}}J$ where joule is the standard unit for energy.
