What is the constant in coulombs law?

The symbol k is a proportionality constant known as the Coulomb’s law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 109 N • m2 / C2.

What is gravity’s constant value?

6.67 ×
Gravitational Constant. In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The direction of the force is in a straight line between the two bodies and is attractive.

What is the relationship between FQ and FG and θ?

In this problem we are given that l and r are equal. Therefore, θ is 30°. If we wish to determine the charge given the angle of the hang. Let us assume in this case that m = 1 gram = 10–3 kg.

Why are inertial and gravitational mass equal?

The mechanism for inertial mass and that for gravitational mass must be mutually consistent. Their equality is the result of their identity, the matter embodying them both, and doing so simultaneously, together, as one.

Why is Coulomb law called an inverse square law?

In Coulomb’s Law, the distance between charges appears in the equation as 1 / r 2 1/r^2 1/r21, slash, r, squared. That makes Coulomb’s Law an example of an inverse square law. It makes intuitive sense that electric force goes down as the distance between two charged bodies increases.

Is the value of g constant in everywhere and why?

Answer: Gravity is assumed to be same everywhere, on earth, but it varies because the planet is not perfectly spherical or uniformly dense. The value of G is 6.67 × 10^11 Nm^2/ kg^2. It is constant everywhere because is it is standard value termed as ( universal gravitational constant).

Why is inertial mass not the same as gravitational mass?

Inertial mass is found by applying a known force to an unknown mass, measuring the acceleration, and applying Newton’s Second Law, m = F/a. To state the answer one more time, there is no difference between gravitational and inertial mass as far as we know.

How does inertial mass differ from gravitational mass?

The key difference between gravitational mass and inertial mass is that gravitational mass is measured under gravity, whereas inertial mass is measured under any force. Mass is a property of a substance as well as its resistance towards acceleration.
