Average speed = distance travelled / time used
I think the answer is D
Hope this helps :D
Answer:
E = 420.9 N/C
Explanation:
According to the given condition:

where,
E = Magnitude of Electric Field = ?
v = speed of charge = 230 m/s
B = Magnitude of Magnetic Field = 0.61 T
θ = Angle between speed and magnetic field = 90°
Therefore,

<u>E = 420.9 N/C</u>
The correct answer for #2 is C the magnetic force will be strongest on box #1.
Answer:
<h2>Electric charge</h2>
Explanation:
The rate of the flow of electric charge is known as electric current. <u>By convention, the direction of electric current is always the direction of net flow of positive charge.</u>
