Answer:
Velocity of the electron = v = 1.2\times 10^8\ m/s.
Explanation:
Given,
- Mass of the electron =
- Charge on the electron =
- Charge density of the ring =
- Radius of the ring = R = 0.70 m
- Distance between the electron ant the center or the ring = x = 0.5 m
Now total charge on the ring = 
Potential energy due to the charged ring to the point on the x-axis is
Let v be the velocity of the electron at the center of the ring.
Total kinetic energy of the electron = 
Now, From the conservation of energy,
the total potential energy of the electron at initially is converted to the total kinetic energy of the electron at the center of the ring,
Hence the velocity of the electron on the center of the charged ring is 
I think this is the right order.

The average speed of the given car is 2.22 s and 3.13 s for 0.25 m and 0.50 m distance respectively.
<h3>How to calculate the Average speed?</h3>
The average speed can be calculated by adding the speed of each trial divided by the number of trials,
For 0.25 m the average speed will be:
For the 0.50 m, the average speed will:
Therefore, the average speed of the given car is 2.22 s and 3.13 s for 0.25 m and 0.50 m distance respectively.

The car's speed is 240km/4hr= 60km/hr.
There's not enough information given in the question to determine its velocity.
Height (y) = 36t - 16t^2, where t = time in seconds (s).
Our height (y) after 1s = 36(1) - 16(1)^2
y = 36 - 16 = 20 ft
So it reached a height of 20 ft during that 1 second, which means that at that 1 second it had a velocity of 20ft/s, since v = d(distance)/t = 20ft/1s
