Aproton moves with a speed of 3.60 106 m/s horizontally, at a right angle to a magnetic field. what magnetic field strength is required to just balance the weight of the proton and keep it moving horizontally? (the mass and charge of the proton are 1.67 ✕ 10−27 kg and 1.60 ✕ 10−19 c, respectively.) b = t

The magnetic field strength is required

Explanation:

Given that,

Speed of proton

Mass of proton

Charge

When a proton moves horizontally, at a right angle to a magnetic field .

Then, the gravitational force balances the magnetic field

Here,

Where, B = magnetic field

q = charge

v = speed

Put the value into the formula

Hence, The magnetic field strength is required

do you have a formula possibly

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
