A concave lens is used to form an image. The diagram shows three incident rays that pass the object and then reach the lens. How
does the lens affect the blue ray, which is incident on a path headed to the focal point on the right?
A. The ray bends outward on a path that traces back to the focal point on the left.
B. The ray bends so that it emerges from the lens travelling parallel to the axis.
C. The ray continues on its path and travels through the focal point on the right.
D. The ray bends outward on a path that traces back to the vertex of the lens.

Answer:
earth
Explanation:
The formula for the orbital period of the moon is given by
As the time period is inversely proportional to the square root of the acceleration due to gravity of the planet.
As the value of acceleration due to gravity on Jupiter is more than the earth, so the period of moon around the earth is large as compared to the period of the moon around the Jupiter when the distance is same.
Answer:
(A) ratio of electric force to weight will be
(b) Electric field will be
Explanation:
We have given mass of bee = 100 mg =
Charge on bee
Electric field E = 100 N/C
Weight of the bee
Electric force on the bee
So the ratio of electric force on the bee and weight is
(B) To hold the bee in air electric force must be equal to weight of bee
So
