What is the formula for velocity selector?
What is velocity selector? The speed of charged particles in velocity selector is v=EB v = E B is the velocity required by the particles to pass through the equipment.
What is velocity selector and derive its equation?
⇒qEˆj=−qv0Bˆj. ⇒v0=EB. In a velocity selector, charged particles must move with a speed of v0=EB. in order to pass through the equipment. Hence, the velocity selector, as its name suggests, allows charged particles with a particular velocity to pass through (hence, selecting particles of a certain velocity).
What is the direction of the electric field in the velocity selector?
A velocity selector is a region in which there is a uniform electric field and a uniform magnetic field. The fields are perpendicular to one another, and perpendicular to the initial velocity of the charged particles that are passing through the region.
What is use of velocity selector Mcq?
Question: A velocity selector is used in a variety of devices to produce a beam of charged particles of uniform velocity.
What is meant velocity selector What is the significance of velocity selector?
Velocity selector is used in accelerator to select charged particle of particular velocity out of a beam containing charges moving with different speeds.
Does a velocity selector work with electrons?
A Wien filter also known as velocity selector is a device consisting of perpendicular electric and magnetic fields that can be used as a velocity filter for charged particles, for example in electron microscopes and spectrometers. It is used in accelerator mass spectrometry to select particles based on their speed.
What is velocity selector derive an expression of velocity of a particle in velocity selector?
In velocity selector two kinds of forces exist. one is electric force F1=qE and another is magnetic force F2=qvB. The idea is that, if the two forces are equal and opposite, the net force is zero, and the particle passes through the region without changing direction.
What is F MA used for?
Newton’s second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration. Created by Sal Khan.
What is velocity selector formula?
1. What is the Velocity Selector Formula? Ans: In the velocity selector, charged particles must move with a speed of v0 = E/B in order to pass through the equipment. This is also known as the velocity selector formula. 2. What is Velocity Selector Physics?
How to find the speed of charged particles in velocity selector?
The speed of charged particles in velocity selector is v = E B v = E B is the velocity required by the particles to pass through the equipment. Uniform electric field: This field is generated by the top plate with negative charges and the bottom plate with the positive charges.
What is velvelocity selector?
Velocity selector is also known as Wien filter is a device with a perpendicular arrangement of electric and magnetic fields which is used as a velocity filter for charged particles. Velocity selector exploits the principle of motion of a charge in a uniform magnetic field.
