Previous Question: A ray of light travelling in water is incident on its surface open to air. The angle of incidence is θ, which is less than the critical angle. Then there will be (A) only a reflected ray and no refracted ray (B) only a refracted ray and no reflected ray (C) a reflected ray and a refracted ray and the angle between them would be less than 180° − 2θ (D) a reflected ray and a refracted ray and the angle between them would be greater than 180° − 2θ Next Question: Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then, (A) negative and distributed uniformly over the surface of the sphere (B) negative and appears only at the point on the sphere closest to the point charge (C) negative and distributed non-uniformly over the entire surface of the sphere (D) zero

Two particle of mass m each are tied at the ends of a light string of length 2a. The
whole system is kept on a frictionless horizontal surface with the string held tight so
that each mass is at a distance ‘a’ from the center P (as shown in the figure). Now, the
mid-point of the string is pulled vertically upwards with a small but constant force F. As
a result, the particles move towards each other on the surface. The magnitude of
acceleration, when the separation between them becomes 2x is: Asked In IIT-JEE MAN (11 years ago); Unsolved; Is this Puzzle helpful? (1) (1) Submit Your Solution
