Answer: The Flash, Allen's top speed is Mach 3.3, or 2,532 miles per hour.
Explanation:
Answer:
Final velocity of electron,
Explanation:
It is given that,
Electric field, E = 1.55 N/C
Initial velocity at point A, 
We need to find the speed of the electron when it reaches point B which is a distance of 0.395 m east of point A. It can be calculated using third equation of motion as :
........(1)
a is the acceleration, 
We know that electric force, F = qE

Use above equation in equation (1) as:


v = 647302.09 m/s
or

So, the final velocity of the electron when it reaches point B is
. Hence, this is the required solution.

Since initial velocity is zero hence , u = 0
=> d = 1/2 * a * t2

on solving we get
d = 86.436 metres
Note ; Here Gravitational Acceleration is take as , g = 9.8 m/s2
Answer:
B. Increases, also B is before C
Explanation:
Answer:
Explanation:
Let the electric field strength is E and the charge is q. The force experienced by the charge due to the presence of electric field is
F = q x E
The direction of force is same as that of the electric field strength if the charge is positive in nature and if the charge is negative in nature the direction of force is opposite to the direction of electric field.
