Answer:

The surface exerts an upward normal force N such that the net vertical force on the mass is

∑ F = N - mg = 0

where m = 2 kg and g is the acceleration due to gravity. So

N = (2 kg) (9.8 m/s²) = 19.6 N

The frictional force then has magnitude µ (19.6 N), where µ is the coefficient of static friction. If the maximum magnitude of static friction is to be 10 N, we have

10 N = µ (19.6 N)

===>   µ = (10 N)/(19.6 N) ≈ 0.51

blsea [12.9K]

We have that the electric field at the center of the metal ball due only to the charges on the surface of the metal ball is

E=7*10^{9}N/C

From the question we are told that

A solid metal ball of radius 1.5 cm

bearing a charge of -15 nC is located near a hollow plastic ball of radius 1.9 cm bearing

uniformly distributed charge of -7 nC

The distance between the centers of the balls is 9 cm

Generally the equation for the electric field  is mathematically given as

E=\frac{kq_2}{d^2}\\\\E=\frac{(9*10^9)7*10^{-2}}{9*10^{-2}}\\\\

E=7*10^{9}N/C
