Aparticle of mass 10 g and charge 72 μc moves through a uniform magnetic field, in a region where the free-fall acceleration is −9.8j m/s2. the velocity of the particle is a constant 19i hat km/s, which is perpendicular to the magnetic field. what, then, is the magnetic field? (express your answer in vector form.)

or 0.07163 T into the page

Explanation:

m = Mass of particle = 10 g

a = Acceleration due to gravity = -9.8j m/s²

v = Velocity of particle = 19i km/s

q = Charge of particle = 72 μC

B = Magnetic field

Here the magnetic and gravitational forces on the particle are applied in the opposite direction so,

The magnetic field is 0.07163 T into the page

they should be similar or the same
