You okay? It is a tough time after the pandemic, and I hope you're all good :>
Answer: Option C
Explanation:
To find the position of the image when an object lies in front of lens, usually three rays are used. One incident ray passes through the focus and would be parallel to the axis after refraction from the lens. Second would just pass through the optical center. Third incident ray would be parallel to the axis and would refract from the lens and pass through the focus on the right hand side. The three rays would be extended in both the directions and we would see where the three rays would intersect. That would be the position of the image.
Thus, the correct option is C.
Answer:
Potential energy increases.
Explanation:
We know that the direction of electric field is from positive to negative charge. As the proton has the positive charge so if it moves in the direction opposite of electric field, it means that the positive charge will move towards the positive region. As the positive charge is attracted towards negative and repelled by the positive charge. So the work done will be negative in bringing the positive charge towards the positive region of the field and potential energy increases in the direction opposite to electric field. As the potential energy decreases in the direction of electric field.
This kind of wave is called a transverse wave.
