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
Answer:
The answer is 'more' as more mass can exert more pressure
As per above given data
initial velocity = 19.3 km/s
final velocity = - 18.8 km/s
now in order to find the change in velocity
Part b)
Now we need to find acceleration
acceleration is given by formula
given that
now the acceleration is given as
so above is the acceleration
