Answer:
- <u>Field Strength: </u>
Any charged body has the capacity to effect any test charge that comes inside its field or region. It can be also defined as,
"The total amount or magnitude of force,F or intensity felt by any unit test charge when it enters an electromagnetic or electric field."
- For an electric field its unit will be, <u>volt per meter or simply V/m.</u>
Explanation:
<u>A unit test charge inside an electric field:</u>
When a unit test charge enters a given parameters or area set by the charged particle then it will surely experience a force,F equal to the magnitude of that charge body and it will be different as it continues to move closer or far inside the field.
- As, we have, "E=F/q",(where "F" is the field strength and "q" is the unit test charge placed inside the field).

<h3>What is acceleration?</h3>
In mechanics, acceleration refers to the rate at which an object's velocity with respect to time varies. Acceleration is a vector quantity (in that they have magnitude and direction). The direction of an object's acceleration is determined by the direction of the net force acting on it. Newton's Second Law states that the combined effect of two factors determines how much an item accelerates:
(i) It follows that the magnitude of the net balance of all external forces acting on the object is directly proportional to the magnitude of this net resulting force, and
(ii) the mass of the thing, depending on the materials out of which it is constructed, is inversely proportional to the mass of the thing.
Calculations:
40 km/hr ----- 11.11m/s
80 km/hr ----- 22.22m/s
Time taken
v-u=at
22.22-11.11= 0.8049 x t
t=13.802s
