Two pellets, each with a charge of 1 microcoulomb (10-6 C), are located 3 cm (0.03 m) apart. What is the electric force between

them? What would be the mass of an object that would experience this same force in the Earth's gravitational field?

Answer:

Therefore the electric force between them is 10 N

Mass of the object that would experience the same force is 1.02 kg.

Explanation:

Coulomb's Law:

The magnitude of electrostatic force of repulsion or attraction between two stationary electrical charged particle is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.

\therefore F=k \frac{q_1q_2}{r^2}

q_1, q_2 are two charges.

r is the distance between the charges q₁ and q₂ .

k=9\times 10^{9}  N m²/C²

Here q_1=q_2=10^{-6} \ C , r = 0.03 m.

\therefore F=9\times 10^{9} .\frac{10^{-6}\times10^{-6}}{(0.03)^2} N

      =10 N

Therefore the electric force between them is 10 N

The formula for gravitation force:

F=mg

m= mass

g= 9.8 m/s²

F=10 N

\therefore 10 = 9.8 \times m

\Rightarrow m=\frac{10}{9.8}

       =1.02 kg

Mass of the object that would experience the same force is 1.02 kg.

Select the correct location on the image.<br> Identify the magnetic north pole of Earth’s magnet.
OverLord2011 [107]

The magnetic north pole of the earth's magnet is in the geographic south pole.

  • There are two magnetic and geographic poles each, north and south
  • The two geographic poles are the locations where the earth's axis of rotation passes through which is imaginary
  • The magnetic north and south poles are not the same as the geographic north and south poles
  • In a compass, the needle points to the magnetic north pole
  • By convention, the magnetic north pole corresponds to the geographic south pole
  • The magnetic south pole corresponds to the geographic north pole
  • The magnetic field lines of a magnet start from the magnetic north pole and end at the magnetic south pole

The magnetic north pole of the earth's magnet is the geographic south pole.
