Nuclear Force

Q. If F Fy Fw and Fe be the gravitational, nuclear, weak and electromagnetic forces respectively, thenarrange them in proper order as per their strength.

Q.

What are natural forces?

Q. Which of the following is incorrect about nuclear force?

1. Neutron & protons are bound in nuclear by short-range strong force
2. Nuclear force does not distinguish between neutron & proton
3. Nuclear force is always attractive
4. Nuclear force is stronger than coulombic force

Q. Briefly explain the weak nuclear force and about the beta decay and anti-nutrino.

Q. What are the carriers? Name the carriers of gravitational force, strong nuclear force, weak nuclear force and electromagnetic force.

Q. At short distances nuclear force is attractive in nature.

1. True
2. False

Q. what is the meaning of beta decay in weak nuclear forces

Q. what is difference between weak nuclear force and strong nuclear force they act in atoms nucleas

Q.

Which of the following statements are correct regarding strong nuclear forces:

1. Strong nuclear forces depend on the charge on the nucleons
2. Strong nuclear forces depend on the spin of the nucleons
3. Strong nuclear force is very short ranged force
4. None of these

Q. Let $F_{pp}$ and $F_{nn}$ denote the net magnitudes of forces between a proton and a proton, a proton and a neutron, and between two neutrons, when they are $1fm$ apart. Which is the correct relation?

1. $F_{pp}=F_{pn}=F_{nn}$
2. $F_{pp}<F_{pn}=F_{nn}$
3. $F_{pp}<F_{pn}<F_{nn}$
4. $F_{pp}=F_{pn}<F_{nn}$

Q. graivitational force isa weakest force and its range is long but nuclear force is astrongest force but its range is short why?

Q. If three ${}^{4}He$ nuclei combine to form a ${}^{12}C$ nucleus, energy is liberated. Why can't helium nuclei combine on their own and minimize the energy?

1. He gas is rare, so collisions between nuclei are also rare;
2. It happens and the ${}^{12}C$ we see in nature was formed by this method only in Earth's atmosphere;
3. The strong nuclear force between nucleons is attractive but short range; the Coulomb force between protons is long range, but repulsive;
4. Helium nucleus is more stable than carbon.

Q. Name the force responsible for the stability of the nuclei a. Strong Nuclear Force b. Weak Nuclear Force c. Electromagnetic Force d. Centripetal Force
