An electron that has an instantaneous velocity of is moving through the uniform magnetic field (a) Find the force on the electron due to the magnetic field. (b) Repeat your calculation for a proton having the same velocity

Explanation:

From the given information:

The missing value are as follows:

The velocity  

The uniform magnetic field

The force on electron as a result of the Magnetic field is:

here;

Change of electron

Then,

∴

For the proton with the same velocity:

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
