x-axis.

b. 5.7x10^{-4} T, in the positive direction of the
x-axis.

c. 1.7x10^{-4} T, in the negative direction of the
x-axis.

d. 1.7x10^{-4} T, in the positive direction of the
x-axis.

Answer #1

Solution :

Assume a charged object with a mass of 9.6 gram moves in the
positive direction of the x- axis with a kinetic energy of 48 kJ.
This object enters in a region of magnetic field of 1.2 mT. If the
charge of this particle is +18 µC and the direction of the magnetic
field is in the positive y-axis, calculate the magnitude and the
direction of the magnetic force act on this object.

A charged particle of mass m = 4.6X10-8 kg, moving
with constant velocity in the y-direction enters a region
containing a constant magnetic field B = 2.3T aligned with the
positive z-axis as shown. The particle enters the region at (x,y) =
(0.79 m, 0) and leaves the region at (x,y) = 0, 0.79 m a time t =
409 μs after it entered the region.
