How does electric force depend on the amount of charge and the distance between charges
Gennadij [26K]
<h2> F = k×\frac{q1q2}{r2}</h2>

Explanation:

  • The attractive or repulsive forces which act between any two charged species is an electric force.
  • The electric force depends on the distance between the charged species and the amount of charge which can be calculated by the formula given as follows  

    F = k×\frac{q1q2}{r2}

where, K is coulombs constant, which is equal to -                                  9 x10^9 Nm^2/C^2.

  • The unit for K is newtons square meters per square coulombs.
  • This is known as Coulomb's Law.

Identify each of the quantities below as either vector or scalar
natta225 [31]

Answer:

2nd answer 3.2m/s is a scalar l, all others are vectors.

Explanation:

In order to be considered as a vector a certain quantity must have both a magnitude and a direction.

The most common example is velocity. It has both magnitude and direction, like the 1st and the last answers.

The 3rd answer is an acceleration. It is also given with its direction. So we have to consider it also as a vector.

But 2nd answer has no direction mentioned, so it is considered as a scalar.
