Is there a gravitational force of attraction between your phone and the earth?

1 answer:

3 0

Yes. When you let go of your phone it will fall to the earth because of Gravitational pull. If it did not exist the phone would float like in space

Two protons are moving up when they enter a magnetic field that points towards you. What happens to the motion of the particles?

Llana [10]

The protons will possess a force pointing to the right.

The force is called Laurentz Force, which is measured by: F = qvB

Here, q is positive for proton, v and B are cross product determined by right hand rule.

When two point charges are a distance d part, the electric force that each one feels from the other has magnitude F. In order to

Contact [7]

Answer:

Because the force is inversely proportional to the square of the distance

Explanation:

The magnitude of the electrostatic force between two charged particles is given by

$F=k\frac{q_1 q_2}{d^2}$

where

k is the Coulomb's constant

q1, q2 are the magnitudes of the two charges

d is the distance between the two charges

We observe that the magnitude of the force is inversely proportional to the square of the distance.

Therefore, when the distance changes to

$d'=\frac{d}{\sqrt{2}}$

The force will double:

$F'=k\frac{q_1 q_2}{(d/\sqrt{2})^2}=2(k\frac{q_1 q_2}{d^2})=2F$

Prove p=f/a science chapter pressure

Shalnov [3]

Explanation:

Let 'F' be force acting perpendicularly, 'A' be the area and 'P' be the pressure exerted.

Then,

Pressure is directly proportional to the the force acting perpendicularly i.e.

P ∝ F ............. (i)

Pressure is inversely proportional to the area on which force acts i.e.

P ∝ 1/A ........... (ii)

Combining equations (i) and (ii),

P ∝ F/A

or, P = K × F/A [where K is a constant]

If F is 1N, A is 1m² and P is 1 N/m², then K is 1.

So, P = F/A proved...
