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

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.
