Answer:
*If the particles are deflected in opposite directions, it implies that their charges must be opposite
*the force is perpendicular to the speed, therefore it describes a circular movement, one in the clockwise direction and the other in the counterclockwise direction.
Explanation:
When a charged particle enters a magnetic field, it is subjected to a force given by
F = q v x B
where bold letters indicate vectors
this expression can be written in the form of a module
F = qv B sin θ
and the direction of the force is given by the right-hand rule.
In our case the magnetic field is perpendicular to the speed, therefore the angle is 90º and the sin 90 = 1
If the particles are deflected in opposite directions, it implies that their charges must be opposite, one positive and the other negative.
Furthermore, the force is perpendicular to the speed, therefore it describes a circular movement, one in the clockwise direction and the other in the counterclockwise direction.

Answer:
The ball will return to the thrower's hand with a speed of 10 m/s
Explanation:
- what is straight upward motion?
It is the motion when an object is projected upward, it moves in the opposite direction of the force of gravity.
The velocity is negative while the object moves up and positive while it moves downward due to upward motion.
Here,
A ball is thrown straight upward, u = 10 m/s
final velocity since ball momentarily stops at highest point, v= 0 m/s
According to Newton's 3rd equation of motion:
where,
g = acceleration due to gravity = -9.8 m/s²
h = height
substituting the values,
2(-9.8)h = (0)² - (10)²
h = 100 / 19.6
h = 5.10 m/s
Now, we consider downward motion:
2gh = v² - u²
where,
g = 9.8 m/s²
h = height = 5.10 m
v = return velocity of ball
u = 0 m/s
substituting the values,
2(9.8)(5.10 m) = V² - (0)²
V = √(99.96)
V = 9.99 m/s
V ≈ 10 m/s
Hence,
the ball will return to the thrower's hand with a speed of 10 m/s
