Answer:
A. Both spheres land at the same time.
Explanation:
The horizontal motion doesn't affect the vertical motion. Since the two spheres have the same initial vertical velocity and same initial height, they land at the same time.
Answer:
A. F=6.65*10^{-10}N
B. south - north
Explanation:
A) We use the Lorentz force
F = qv X B
|F| = qvB
to calculate the magnitude of the force we need the speed of the of the ball.
and by replacing in the formula for the magnitude of the force we have (taking into account the excess of electrons)
B)
b. south - north (by the rigth hand rule)
I hope this is usefull for you

Answer:
A
Explanation:
The line(A) goes throughout the entire picture. So therefore choice A would be it's length.
Current = charge per second
2 Coulombs per second = 2 Amperes
Potential difference = (current)x(resistance) in volts.
That's (2 Amperes) x (2 ohms).
That's how to do it.
I think you can find the answer now.
