Answer:9.8 m/s²
Explanation:
It was going at 9.8m/s² as this is the acceleration of an object due to gravity
when an object falls it accelerates at a consant and uniform speed which is 9.8m/s²
Answer:
The force between the charges are not affected.
Explanation:
Given;
distance between two equal charges, R = 2m
The force between the charges is given by;

Therefore, the force between the charges are not affected.
Answer:
Newton's Universal Law of Gravitation: 'a simple equation, but devastatingly effective'. ... The equation says that the force (F) between two objects is proportional to the product of their masses (m1 and m2), divided by the square of the distance between them.

Answer:
The magnitude of magnetic field is 0.312 T and direction of the magnetic field is out of the page.
Explanation:
Given:
Velocity of proton

Magnetic force
N
Charge of proton
C
The magnetic force experience by proton in magnetic field is given by,

Here magnetic force experienced by proton is maximum so we take 



T
According to the left hand rule the direction of magnetic field is out of the page.
Therefore, the magnitude of magnetic field is 0.312 T and direction of the magnetic field is out of the page.
