Five balls numbered 1,2,3,4,and 5 are suspended using separated threads. The balls (1,2),(2,4) and (4,1) show electrostatic attraction while balls (2,3) and (4,5) show repulsion. Therefore, ball 1 must be

Five balss numbered 1,2,3,4,and 5 are suspended using separated threads. The balls (1,2),(2,4) and (4,1) show electrostatic attraction while balls (2,3) and (4,5) show repulsion. Therefore, ball 1 must be

Five balls numbered 1 to 5 are suspended using separate threads. Pairs (1,2), (2,4) and (4,1) show electrostatic attraction whilt pairs (2,3), (4,5) show repulsion. Therefore, ball 1 must be

Five balls numbered 1 to 5 are suspended using separate threads. Pairs (5,3), (3, 4) and (4, 5) show electrostatic attraction, while pairs (2, 3) and (4, 1) show repulsion. Therefore ball 5 must be

Five balls numbered 1 to 5 are suspends using separate threads Pairs (1,2) , (2,4) and (4,1) show electrostaic attraction while pairs (2,3) and (4,5) show repulsion Therefore ball 1 must be

Five balls numbered 1 to 5 are suspended using separate threads. The pairs of balls (1, 2),(2, 4) and (5, 1) show attraction while the pairs (2, 3) and (4, 5) show repulsion. The ball 1 is:

Four charged balls numbered 1 to 4 are suspended using separate threads. Pairs (1,2) and (1,3) show repulsion, while pair (2,4) shows attraction. If ball 4 is now brought near balls 1 and 3, it will be respectively

Five balls marked by numbers from 1 to 5 are hung by different threads. It is seen that the pairs of the balls (1,2), (2, 4), (4,1) attract each other. Again the pairs (2,3) and (4,5) repel each other. So the ball marked by 1 is

Four balls numbered 1,2,3,4 are to be placed into five boxes numbered 1,2,3,4,5, such that exactly one box remains empty and no ball goes to its own numbered box.The no.of ways is

A box B_(1) contains 1 white ball, 3 red balls, and 2 black balls. An- other box B_(2) contains 2 white balls, 3 red balls and 4 black balls. A third box B_(3) contains 3 white balls, 4 red balls, and 5 black balls. If 1 ball is drawn from each of the boxes B_(1),B_(2) and B_(3), the probability that all 3 drawn balls are of the same color is
