Answer:
E = 0 r <R₁
Explanation:
If we use Gauss's law
Ф = ∫ E. dA = / ε₀
in this case the charge is distributed throughout the spherical shell and as we are asked for the field for a radius smaller than the radius of the spherical shell, therefore, THERE ARE NO CHARGES INSIDE this surface.
Consequently by Gauss's law the electric field is ZERO
E = 0 r <R₁

Answer:
Net acceleration = 3.5m/s²
Explanation:
Given the following data;
Mass, m = 40kg
Normal force, Fn = 400N
Applied force, Fapp = 195N
Force of friction, Ff = 55N
Mathematically, the net force is given by the formula;
Substituting into the equation, we have;
<em>To find the acceleration;</em>
Making acceleration "a" the subject of formula;
Net acceleration, a = 3.5m/s²
Answer:
the solid particles that settle down at the bottom of the container are known as sediment.
Explanation:
Answer:
The object would weight 63 N on the Earth surface
Explanation:
We can use the general expression for the gravitational force between two objects to solve this problem, considering that in both cases, the mass of the Earth is the same. Notice as well that we know the gravitational force (weight) of the object at 3200 km from the Earth surface, which is (3200 + 6400 = 9600 km) from the center of the Earth:
Now, if the body is on the surface of the Earth, its weight (w) would be:
Now we can divide term by term the two equations above, to cancel out common factors and end up with a simple proportion:
