## What is the SI unit of susceptibility *?

Mass-normalized susceptibility (χ) equal to volume susceptibility divided by the density of the sample, in SI units of m3/kg..

## What is a SI unit of charge?

The SI derived unit of electric charge is the coulomb, which is defined as an ampere second.

## What is the SI unit of electromagnetic induction?

teslaThe SI unit of magnetic induction (B) is tesla. One tesla is equal to one weber per metre square.

## What is the SI unit of Coulomb?

Coulomb, unit of electric charge in the metre-kilogram-second-ampere system, the basis of the SI system of physical units. It is abbreviated as C. The coulomb is defined as the quantity of electricity transported in one second by a current of one ampere.

## What is SI unit of Q?

Explanation: The coulomb, C , is derived from the fundamental SI unit of time, the second, s , and the fundamental SI unit of electric current, the ampere, A . It is the charge (Q or q) transported by a constant current of one ampere in one second.

## Which is the strongest force?

The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.

## What are the main forces?

According to the present understanding, there are four fundamental interactions or forces: gravitation, electromagnetism, the weak interaction, and the strong interaction. Their magnitude and behaviour vary greatly, as described in the table below.

## What are the universal forces?

The four fundamental forces, also known as the Universal forces are electromagnetic force, strong nuclear force, weak nuclear force, and gravitation. … The strong nuclear force acts over a small distance while gravity acts over a long distance. Scientists have been trying to combine all forces into one.

## What is SI unit of voltage?

In SI base units: kg·m2·s−3·A−1. The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force. It is named after the Italian physicist Alessandro Volta (1745–1827).

## What are the 7 basic SI units?

The seven SI base units, which are comprised of:Length – meter (m)Time – second (s)Amount of substance – mole (mole)Electric current – ampere (A)Temperature – kelvin (K)Luminous intensity – candela (cd)Mass – kilogram (kg)

## What is the unit of electromagnetic force?

It is commonly measured in units of volts, equivalent in the metre–kilogram–second system to one joule per coulomb of electric charge. In the electrostatic units of the centimetre–gram–second system, the unit of electromotive force is the statvolt, or one erg per electrostatic unit of charge.

## What is the formula of electromagnetic force?

Charges confined to wires can also experience a force in a magnetic field. A current (I) in a magnetic field ( B) experiences a force ( F) given by the equation F = I l × B or F = IlB sin θ, where l is the length of the wire, represented by a vector pointing in the direction of the current.

## What are the 4 fundamental forces?

Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.
