Explanation:
Given that,
Orginal speed, u = 10,000 m/s
Final speed, v = 5,000 m/s
Time, t = 60 s
To find,
Acceleration of the satellite.
The acceleration of an object is equal to the change in its speed divided by time. So,
So, the acceleration of the satellite is and it is deaccelerating.
Explanation:
It is given that, an electron and a proton are separated by a distance of 1.0 m i.e d = 1 m . At this position, F is the force between them
...............(1)
We need to find effect on force between them if the electron moves 0.5 m away from the proton. Let the force is F'.
...............(2)
On dividing equation (1) and (2) we get :
F' = 4 F
So, the distance between the electron and the proton is 0.5 m, the new force will be 4 times of previous force.
