Log in to keep practising for free.
Explanation
The length of galaxies is typically in the order of $10^{21} m$ to $10^{25} m$. Therefore, the closest option is $10^{26} m$.

Explanation
The charge of an electron is approximately $1.6 imes 10^{-19} C$. Hence, the correct value is $10^{-19} C$.
The ............... force is the strongest of all fundamental forces

Log in to keep practising for free.
Explanation
The strongest of all fundamental forces is the nuclear force, also known as the strong nuclear force. It is responsible for holding the nuclei of atoms together and is much stronger than the other fundamental forces.
Which of the following force binds The particle in the nucleons ?

Log in to keep practising for free.
Explanation
The force that binds particles in the nucleons (protons and neutrons) is the strong force, also known as the strong nuclear force. This is one of the four fundamental forces of nature and is responsible for holding the nuclei of atoms together. It is much stronger than the electromagnetic force, although it acts over a very short range.

Which partical are emitted during the $ \beta $ decay from the nucleus ?
You've reached today's free limit of 20 questions.
Log in to keep practising for free.
Explanation
In beta decay, a neutron in the nucleus is converted into a proton, an electron, and an antineutrino (or a proton is converted into a neutron, a positron, and a neutrino in beta-plus decay). Therefore, the particles emitted are an electron and a neutrino (or antineutrino).
............... and ............... law’s are called inverse square law
You've reached today's free limit of 20 questions.
Log in to keep practising for free.
Explanation
The gravitational law (Newton's law of gravitation) and Coulomb's law (which describes the force between two charges) are both inverse square laws. This means that the force decreases proportionally to the square of the distance between the two objects or charges.
Which property of object is responsible for the Gravitational force.
You've reached today's free limit of 20 questions.
Log in to keep practising for free.
Explanation
The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This relationship is described by Newton's Universal Law of Gravitation. Hence, mass is the property responsible for gravitational force.
How much times is the strong nuclear force stronger then weak nuclear force ?

Explanation
$ { Strong nuclear force \over Electro magnatic force } = { 1 \over 10 ^ {-2 } } = 10 ^ 2 $
