As per the question the uncharged pith ball is taken towards the electrostatic field of a charged rod.
It is told that the side of the pith ball is closest to the negatively charged end of the rod .
The pith ball was initially neutral.The electrons in the atom were oriented in their respective orbits.
Whenever it is taken towards the negative end of the rod,the electrons present in the ball will not stick to their orbit .Basically the closest electrons will suffer electrostatic repulsive force and will come out their orbits.They will move towards the other end of the pith ball.Hence the closest side of the pith ball will acquire positive charges and other side will be negative.
The bound charges nearest to the charged rod is called induced positive charges and bound negative charges present at the other end are called free bound charges.The induced charges and free charges are equal in amount.Hence the pith ball is neutral.
Hence from above we see that only option B is right.
Answer:
James Chadwick
Explanation:
James Chadwick discovered that the nucleus of each atom contains neutrons in 1932. Shortly after this, Eugene Wigner suggested that the electromagnetic force is not involved in holding the nucleus together and that there are two different nuclear forces. We now refer to these as the strong and weak nuclear forces.
Where’s the graph? I don’t see anything
Answer:
wood
Explanation:
you can last longer with wood because you are using up gas when you drive your car that will mean that you will have to go and find gas if you run out an example like we are in the zombie apocalypse.
2.5N
Explanation:
Given parameters:
Mass of object = 500g
Acceleration = 5m/s²
unknown:
Resultant force = ?
Solution:
According to Newton's second law "the net force on a body or the resultant force is the product of its mass and acceleration".
Resultant or net force = m x a
where m is the mass
a is the acceleration
Now we need to convert the mass to kg
1000g = 1kg
500g = 
= 0.5kg
Therefore;
Input the parameters:
Force = 0.5 x 5 = 2.5N
