<h2>Answer</h2>
Option A that is 8.8 × 10^3 m/s
<h2>Explanation</h2>
The magnetic field B is defined from the Lorentz Force Law, and specifically from the magnetic force on a moving charge. It says
Field-strength = BVqsinΔ
<h2>v = E/B </h2>
Since field are perpendicular so sin90 = 1
v = 4.6/10^4 / 5.2
v = 8846.15 m /s
The speed at which electrons pass through the selector without deflection = 8846.15 m /s
Answer:
5Hz
Explanation:
Frequency = No. of waves per second
10 waves are produced in 2 seconds
in one second 10/2 waves are produced
(ie) 5 waves are produced in 1 second
Therefore the frequency of wave is 5 Hz
