The correct answer is:
sixteen times
In fact, the distance between charge q and the source S is 1 unit. Instead, the distance between charge p and the source S is 4 units. The magnitude of the electrostatic force is inversely proportional to the square of the distance between the charge and the source:
where r is the distance. If we take the force between q and S as reference, we have r=1, so that
while the force between p and S is
Therefore, we see that the force exerted between q and S is 16 times the force exerted between p and S.
Answer:
Explanation:
Given
Electrostatic force between two electrons is equal to weight of one electron
i.e.
where 
are the charge of particles
mass of electron
r=distance between them
Answer:
The speed of the football when it lift your hand is 8.86 m/s.
Explanation:
Given that,
Final speed of the football, v = 0.5 m/s
Height above the ground, s = 4 m
We need to find the speed of the football when it left your hand. The ball will move under the action of gravity. Using third equation of motion as:
So, the speed of the football when it lift your hand is 8.86 m/s. Hence, this is the required solution.
Answer:
ventriculoperitoneal
Explanation:
A VP or ventriculoperitoneal shunt is a medical equipment or a device which is used to relieve pressure from the brain that is caused by the accumulation of fluid in the brain. Ventriculoperitoneal shunting is a medical procedure that is primarily used to treat a condition known as hydrocephalus. This condition occurs when the more cerebrospinal fluid (CSF) gets collected in the ventricles of the brain than required.
Hence the answer is ---
ventriculoperitoneal
