Answer:
Explanation:
From the question we are told that
The electric filed is
Generally according to Gauss law
=>
Given that the electric field is pointing downward , the equation become
Here is the excess charge on the surface of the earth
is the surface area of the of the earth which is mathematically represented as
Where r is the radius of the earth which has a value
substituting values
So
Here s the permitivity of free space with value
substituting values
Explanation:
It is known that relation between force and acceleration is as follows.
F =
I is given that, mass is 1090 kg and acceleration is 21 m/s. Therefore, we will calculate force as follows.
F =
=
= 1430.625 N
Also, it is known that
= 7.70 degrees
Thus, we can conclude that the maximum steepness for the car to still be able to accelerate is 7.70 degrees.
