Answer:
The magnetic field that will allow the electron to go through the region without being deflected is
.
Explanation:
Given that,
Velocity of the electron, 
Electric field, 
We need to find the magnetic field that will allow the electron to go through the region without being deflected. It can be calculated as :

Here, 

So, the magnetic field that will allow the electron to go through the region without being deflected is
.
Answer:

Given:
Initial velocity (u) = 0 m/s (Starts from rest)
Final velocity (v) = 24 m/s
Time taken (t) = 6 seconds
To Find:
Distance travelled by car (s)
Explanation:
From equation of motion of object moving with uniform acceleration in straight line we have:

By substituting value of v, u & t in the equation we get:


Distance travelled by car (s) = 72 m
Answer:
The correct equation for calculating force is change in momentum divided by time. So 10 kg m/s divided by 3 s is 3.3 newtons (N
