Answer:
15.9 n/m
Step-by-step explanation:
mass of ball,m = 50g = 0.05 kg.
radius of spherical ball, r = 5 cm = 0.05m surface area of spherical ball, A=4πr^2
= 4x 3.14 x (0.05)
= 4x 3.14x 25 x 104
= 3.14 x 10-2 m
Now, pressure = weight of ball/surface area of ball
= (0.05 x 10)/(3.14 x 10^-2)
= 15.9n/m
