A boy throws a table tennis ball of mass 20 g upwards with a velocity of u 0 = 10 m/s at an angle q 0 with
the vertical. The wind imparts a horizontal force of 0.08 N, so that the ball returns to the starting point.
Then, the angle q 0 must be such that, tan q 0 is
(A) 0.2 (B) 0.4 (C) 2.5 (D) 1.2
plss reply fast with appropriate explaination....
