Question

a mass of brake is 5kg its dimensions 10 cm into 5 cm into two what will be the minimum and maximum pressure exerted by it on the ground is resting upon​

Answer 1

Explanation:

we know pressure is inversly proportional surface area

and pressure(P)= F/A. here F= mg=5×10=50N {g=10 ms^-2}

maximum pressure =50/(2×5×10^-4)=5×10^4 Pa

minimum pressure=50/(10×5×10^-4)=10^4 Pa
