In a 1.35 T magnetic field directed vertically upward, a particle having a charge of magnitude 8.50 μC and initially moving northward at 4.68 km/s is deflected toward the east.

a. What is the sign of the charge of this particle? Make a sketch to illustrate how you found your answer.
b. Find the magnetic force on the particle.

a

The sign on the charge is positive sign

According to Flemmings Left Hand rule

     The index finger which represents the Magnetic field(From the question ) is pointing vertically upward so the middle finger would be pointing east ward i.e in the positive x-axis and the  thumb also would be pointing toward east and it represents the force acting on the charge

    The diagram that illustrates this is shown in the first uploaded image

b

The magnetic force is given as  

Explanation:

From the question we are told that

         The magnitude of the magnetic field is

         The  magnitude of the charge is  

          The speed is  

Generally the force is mathematically represented as

Substituting values

come closer and become far apart and become steam/gas

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
