The potential difference between a and b is the energy/unit charge: ie. the energy that a unit charge gains in moving from a to b. The energy that a charge of e gains in moving through a potential difference of 1 volt is 1 eV. So what is the energy that a +2e charge gains in moving from a to b?gekdvb said:point a is at a potentiall of +290...point b is at potential of -220...helium nucleus contains 2 neutrons and 2 protons...neutrons are electrically neutral...what kinetic energy does particle have after accelerating from rest at point a to b...in electron volts

Kinetic energy is the energy an object possesses due to its motion.
Electron volts (eV) are a unit of energy commonly used in the field of physics, particularly in the study of atoms and subatomic particles. One electron volt is equivalent to the amount of kinetic energy gained by an electron when it is accelerated through a potential difference of one volt. In other words, one eV is equal to 1.602 x 10^-19 joules (J).
To calculate the kinetic energy of an object in electron volts, you can use the formula KE = 0.5mv^2, where m is the mass of the object in kilograms and v is the velocity of the object in meters per second. Once you have calculated the kinetic energy in joules, you can convert it to electron volts by dividing by 1.602 x 10^-19.
Using electron volts to measure kinetic energy allows for more precise calculations in the study of subatomic particles and atoms. Since these particles have very small masses and velocities, measuring their kinetic energy in joules would result in very small numbers. Electron volts provide a more convenient and practical unit for these types of calculations.
Yes, kinetic energy can be converted into electron volts by dividing the value in joules by 1.602 x 10^-19. Similarly, electron volts can be converted into joules by multiplying by 1.602 x 10^-19.
