Answer:

The force of friction is 2 N. The object isn't moving.

Explanation:

The frictional force on a object is given by it's normal force multiplied by the coefficient of static friction between the object and the surface. In this case since the surface is horizontal, the normal force is equal to the weight of the block with the oposite direction. So we have:

F_friction = 0.5*N = 0.5*(10) = 5 N

Since the friction force is oposite to force that's acting on the block and it's greater than that force, the object won't move and the real force will be the same as the applied force. So we have:

F_friction = 2 N

A thin metallic spherical shell of radius 0.357 m has a total charge of 5.03 times 10^-6 C placed on it. At the center of the sh
Artyom0805 [142]

Answer:

The electric field is 5.623\times10^{4}\ N/C

Explanation:

Given that,

Radius = 0.357 m

Charge Q=5.03\times10^{-6}\ C

Point charge q=4.15\times10^{-6}\ C

Distance = 0.815 m

We need to calculate the total electric field

Using formula of electric field

E=\dfrac{1}{4\pi\epsilon_{0}}\dfrac{q}{r^2}

Where, q = point charge

r = distance

Put the value into the formula

E=\dfrac{9\times10^{9}\times4.15\times10^{-6}}{(0.815)^2}

E=5.623\times10^{4}\ N/C

Hence, The electric field is 5.623\times10^{4}\ N/C
