The correct answer is: a. 4800 eV

Physics is filled with awe-inspiring phenomena and calculations that drive our understanding of the universe. In this challenge, we delved into the concept of kinetic energy and electric potential to determine the energy of a Li ion.

Kinetic energy is the energy possessed by an object or particle due to its motion. When a charged particle, such as a Li ion with a charge of +1, accelerates through an electric potential difference, it gains kinetic energy.

To calculate the kinetic energy of the Li ion, we use the formula K = qV, where K is the kinetic energy, q is the charge, and V is the potential difference. Given that the charge of a Li ion is +1 and the potential difference is 4800 V, we simply multiply these values to find the kinetic energy.

Therefore, the kinetic energy of the Li ion accelerating through a potential difference of 4800 V is calculated as follows: K = (1)(4800) = 4800 eV. This exhilarating calculation showcases the direct relationship between electric potential and the energy of moving particles.

By mastering physics calculations like these, we unlock the secrets of the universe and unravel the mysteries of motion, energy, and matter. Keep exploring the wonders of physics and enjoy the thrill of solving challenging problems!
