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
