Concept explainers
(a)
The kinetic energy acquired by proton.
(a)
Answer to Problem 55GP
The proton gains the same kinetic energy,
Explanation of Solution
Introduction:
(Kinetic energy) KE of an object is energy that it possesses due to its motion. In other words, the energy of motion is known s kinetic energy. Kinetic energy depends on mass and speed and also, it is measured Joules.It is given that an electron starting from rest acquires
The proton is accelerated through the opposite potential difference (PD) as an electron. Also, it has exact opposite charge.
So, the proton will gain the same KE.
(b)
Ratio of the speed.
(b)
Answer to Problem 55GP
Explanation of Solution
Given data:
Proton and electron have the same kinetic energy.
Mass of proton is
Mass of electron is
Formula used:
The energy of motion is known s kinetic energy. The formula of kinetic energy is
Where,
Calculation:
According to the question, electron and proton has the same kinetic energy. To find the ratio of the speed, use the formula of kinetic energy.
