Question

Which of the following property of a proton can change while it moves freely in a magnetic field??
(a)mass
(b)speed
(c)velocity
(d)momentum
Explain (×_×)

Answer 1

Answer:

c) velocity and d) momentum because when a charged particle is put into a magnetic field then force applied on it and the force was calculated by Fleming's left hand rule.

I hope it will help u

Answer 2

Answer:

The correct answers of this question is option c and d.

Explanation:

When a proton enters in any magnetic field then the magnetic force of that magnetic field perpendicularly works upon that proton which entered in magnetic field.

As a result,the the direction of that proton's velocity changes.

And we all know that velocity is a vector quantity and it has both direction and magnitude.

So if we change the direction then the allover value of the velocity will also change.

And the momentum is another vector unit which is dependent on the value of the velocity ,if the velocity's value changes then the change of the momentum's value is obvious.
