Which statement is true about a farsighted (hyperopic) eye?
a. the image point is in front of the retina; a converging eyeglass lens is used to correct this condition.
b. the image point is in front of the retina; a diverging eyeglass lens is used to correct this condition.
c. the image point is behind the retina; a converging eyeglass lens is used to correct this condition.
d. the image point is behind the retina; a diverging eyeglass lens is used to correct this condition.

The correct answer is C. I leave an attached image to have a clearer idea of the light process that uses the Light when entering the eye. When you have farsightedness, the image is formed behind the eye so the defective effect is generated.

What is sought with the lenses is to correct this condition and put the image back at the point of the retina.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

because growing process had stoped after 4-5 year
