A small object with charge moves on a friction less horizontal plane surface, under the influence of a uniform electric field Ē. And due to the force qE, its speed increases. From zero to 9ms¹ in one second. Now at that instant the direction of the field is reversed, the object continues to move for 2 more seconds under the influence of this field. The average velocity and the average speed of the object between zero to four seconds are respectively.?

A small object with charge moves on a friction less horizontal plane s...
Initial conditions:
- The object starts from rest with zero initial velocity.
- The electric field Ē is uniform and constant throughout the motion.
- The object has a charge q.
- The surface is frictionless.

Acceleration of the object:
- The force experienced by the object due to the electric field is given by the equation F = qE, where F is the force, q is the charge, and E is the electric field.
- According to Newton's second law, F = ma, where m is the mass of the object and a is its acceleration.
- Therefore, qE = ma, which implies a = qE/m.
- Since the mass of the object is not given, we can assume it to be m for simplicity.

Motion of the object:
- From the given information, we know that the object's speed increases from zero to 9 m/s in one second.
- Using the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time, we can find the acceleration.
- Plugging in the given values, we get 9 = 0 + a(1), which gives a = 9 m/s².
- Now, we can use the equation v = u + at to find the final velocity after 4 seconds.
- Plugging in the values, we get v = 0 + 9(4) = 36 m/s.

Average velocity:
- Average velocity is defined as the total displacement divided by the total time taken.
- Since the object starts from rest and moves in a straight line, its displacement is equal to the distance traveled.
- The distance traveled by the object in 4 seconds can be calculated using the equation s = ut + 0.5at², where s is the distance, u is the initial velocity, a is the acceleration, and t is the time.
- Plugging in the values, we get s = 0(4) + 0.5(9)(4)² = 72 m.
- Therefore, the average velocity is 72/4 = 18 m/s.

Average speed:
- Average speed is defined as the total distance traveled divided by the total time taken.
- The total distance traveled by the object in 4 seconds is 72 m, as calculated above.
- Therefore, the average speed is 72/4 = 18 m/s.

Summary:
- The object's speed increases from zero to 9 m/s in one second under the influence of the electric field.
- The direction of the field is then reversed, and the object continues to move for 2 more seconds.
- The average velocity of the object between zero to four seconds is 18 m/s.
- The average speed of the object between zero to four seconds is also 18 m/s.
