उत्तर
Force exerted , F = 1.5 N
Area of cross - section of tip of nail A , a1 = 2 mm2 = `2 xx 10^-6` m2
Area of cross - section of tip of nail B , a1 = 6 mm2 = `6 xx 10^-6 "m"^2`
Pressure on nail A = `"F"/"a"_1 = 1.5/(2 xx 10^-6) = 7.5 xx 10^5` pascal
Pressure on nail B = `"F"/"a"_2 = 1.5/(6 xx 10^-6) = 2.5 xx 10^5` pascal
