Problem 5 Easy Difficulty

The nucleus of $^{8} \mathrm{Be},$ which consists of 4 protons and 4 neutrons, is very unstable and spontaneously breaks into two alpha particles (helium nuclei, each consisting of 2 protons and 2 neutrons). (a) What is the force between the two alpha particles when they are $5.00 \times 10^{-15} \mathrm{m}$ apart, and (b) what is the initial magnitude of the acceleration of the alpha particles due to this force? Note that the mass of an alpha particle is 13 4.0026 $\mathrm{u} .$

Answer

a. 36.8 $\mathrm{N}$
b. $5.54 \times 10^{27} \mathrm{m} / \mathrm{s}^{2}$

Electric Charge

In physics, a charge is a physical property of matter that causes it to experience a force when placed in an electromagnetic field. Electric charge is a characteristic property of many subatomic particles, which determines their electromagnetic interactions. Electrically charged matter is influenced by, and produces, electromagnetic fields. The interaction between a moving charge and the electromagnetic field is the source of the electromagnetic force, which is one of the four fundamental forces.

The Electric Force

The electric force is a physical force exerted by electrically charged particles, and is the force responsible for a number of phenomena in electromagnetism. The electric force plays a major role in determining the internal properties of most objects encountered in daily life. The electric force is one of the four fundamental forces (the others are the strong force, the weak force, and gravity) of nature, and is responsible for a wide range of phenomena, such as the interactions between the components of atoms and molecules, and the formation of molecular bonds and chemical compounds. The electric force is carried by elementary particles called electrons, protons and neutrons. The electric force is responsible for maintaining the cohesion of atoms and molecules, and keeping atoms and molecules together, even though electrically neutral atoms tend to repel each other. The electric force is also responsible for the phenomenon of electricity, including lightning, static electricity, and the flow of electrical current in a conductor such as a wire. In addition, the electric force plays an essential role in maintaining the structure of matter, by keeping the nucleus of the atom together, and by preventing electrically neutral atoms from collapsing into each other.

the force between a tool for particle is given by physical too. Okay, Constant times to e. Oh, this will be square divided by our square student values 8.99 times 10 to the power nine times are four times 1.6 times 10 to the power. Minus 19 is the charge on each alpha particle off square, divided by the distance that is a five times gentle power minus 15 meters square. Disc uses the force off a 36.8 Newton than the exploration produced by this force can be written is a selection physical force divided by the mass force. We just found his 36.8 Newton divided by Mass so converting the atomic mass unit into kilograms. That means been Hying four. When 00 to six times 1.66 times tent about 24 7 This whole factor divides. This uses that explanation off from ex elation of 5.54 times 10 to the power 27 meter for second square
