What is the acceleration of the proton?

Homework Statement. A proton (+e) accelerates from rest in a uniform electric field of 640 N/C. At some later time, the proton’s speed is 1.20 x 10^6 m/s.

How do you find the acceleration of a particle in a magnetic field?

Hence, a=QVB/M. where Q is the magnitude of charge, V is it’s velocity, X is the angle made by the direction of magnetic field and the direction of motion of charge, and B is the magnitude of the magnetic field. To find the acceleration, we need to divide this quantity by the mass of the charged particle/particles.

What is the speed of the moving protons?

The speed of the proton must be 2.12 ×10³ m/s. Let me and ve represent the mass and velocity of the electron.

What is the mass for a proton?

proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.

Is there acceleration in a magnetic field?

You are correct that a charged particle moving in a magnetic field will experience a force such that the direction of its velocity changes but not its speed. This still constitutes acceleration since acceleration is the rate of change of velocity and changing direction of motion means changing velocity.

How do you find the acceleration of a particle in an electric field?

The value of the acceleration can be found by drawing a free-body diagram (one force, F = qE) and applying Newton’s second law. This says: qE = ma, so the acceleration is a = qE / m.

How do you find the acceleration of an electric field?

How do you find the speed of a proton?

To do this, let’s multiply both sides by 𝑣 divided by 𝜆 B. This cancels out the de Broglie wavelength on the left. And it cancels out the speed 𝑣 on the right. So then, the proton speed we want to solve for is equal to Planck’s constant divided by the mass of the proton times its de Broglie wavelength.
