Answer:
The electric flux is zero because charge is zero.
Explanation:
Given that,
Positive charge
Negative charge
We need to calculate the total charged
Using formula of charge
Put the value into the formula
We need to calculate the electric flux
Using formula of electric flux
Put the value into the formula
Hence, The electric flux is zero because charge is zero.
Answer:
Final velocity of the car will be -9.28 m/sec
Explanation:
We have given that the car starts from the rest so initial velocity of the car u = 0 m /sec
Acceleration of the car in negative direction so acceleration will be
From first equation of motion we know that
v = u+at
So
So final velocity will be -9.28 m/sec
