1.	5 pa os pressure is required to be exerted on an are of250 m^2 .A box is placedon that area and the surface of cantact is exactly 250 m^2 .What should be the mass of the box so that exactly 5 pa of pressure can be exerted ?
Answer» Solution :`Pressure ="Force"/"AREA" ` `5 = "Force "/250 (1 "PA" = 1 N//m ^2)` `therefore` R reqired force= 1250 N LET m be the mass of the OBJECT `therefore m xx g = 1250` `therefore m xx 10=1250` `therefore m= 1250/10 kg = 125 kg""(because g ~~ 10 m s^(-2))`
