I believe gamma decay but i may be wrong
Answer:
The correct option is;
A. The potential energy between both like charges and like poles increases as they move closer together
Explanation:
Here we have that when we move the like poles of two bar magnets close to each other, there is an increased resistance in the continuing motion, therefore for each extra gap closer achieved, there is an increase in potential energy
Similarly, when two like charges are brought closer together, the potential energy, or the energy available to push the two like charges apart increases charge as the as the charges are brought closer together
Therefore, the correct option is the potential energy between both like charges and like poles increases as they move closer together.
Answer:
If the particle is an electron 
If the particle is a proton, 
Explanation:
Initial speed at the origin, 
to +ve x-axis
The particle crosses the x-axis at , x = 1.5 cm = 0.015 m
The particle can either be an electron or a proton:
Mass of an electron, 
Mass of a proton, 
The electric field intensity along the positive y axis
, can be given by the formula:

If the particle is an electron:



If the particle is a proton:



Answer:
A. They diverge on refraction
Explanation:
- The concave lens has the physical characteristics that both sides are curved inwardly. Due to this physical nature, the lens is thicker towards the outer circumference.
- Due to such physical characteristics of a concave lens, when parallel light rays strike on a concave lens, it is refracted and diverge out from the other side.
- When the diverging rays are traced back, it seems as if the rays are appearing from a point.
- This point is where the rays seem to appear is called the principal focus of the lens.
- Thus the image formed by the concave lens is erect, virtual and diminished.
