Q1:  Bhola was impressed by the miracle performed by Baba Bandar Nath when Baba lied down on a bed of nails. The nails did not hurt him. Bhola narrated about this miracle to his friend Rithik. Rithik explained to Bhola that there is no magic or miracle here. Even he can also do the same trick.

(a) Why did Rithik say that there is no 'miracle' in this trick? Why did Baba Bandar Nath did not hurt himself?
(b) Which quality is shown by Rithik here?

Answer:
(a) Rithik is right that there is no miracle here. We know that pressure is defined as force acting per unit area. If you step up on a nail, the entire body weight exerts more pressure because the area of nail tip is very small. In case of bed of nails, the pressure exerted by the weight of the body is distributed among the hundreds or thousands of nails lying close to each other. Thus the net pressure on a nail is very small.
