Question: The force between a pair of 0.005 C is 750 N. What is the distance between them?

Answer:

17.32 m

Explanation:

From coulomb's Law,

F = kqq'/r²........................... Equation 1

Where F = Force between the force, q' and q = both charges respectively, k = coulomb's constant, r = distance between both charges.

make r the subject of the equation above

r = √(kqq'/F)..................... Equation 2

From the question,

Given: q = q' = 0.005 C, F = 750 N

Constant: k = 9.0×10⁹ Nm²/C².

Substitute these values into equation 2

r = √(9.0×10⁹×0.005×0.005/750)

r = √(300)

r = 17.32 m.

Hence the distance between the pair of charges = 17.32 m

Morgarella [4.7K]

Answer:

3.6×10⁶ m

Explanation:

g = GM / R²

4 m/s² = (6.67×10⁻¹¹ m³/kg/s²) (6×10²⁴ kg) / (6.4×10⁶ m + h)²

(6.4×10⁶ m + h)² = 1.00×10¹⁴ m²

6.4×10⁶ m + h = 1.00×10⁷ m

h = 3.6×10⁶ m

When the light from a light bulb is reflected by a diffraction grating, a continuous band spectrum is obtained (like a rainbow).

MA_775_DIABLO [31]

Answer:

The light of a light bulb contains all the wavelengths of visible band which on passing through diffraction grating appear in the form of continuous spectra.

Discrete lines are observed when the electron makes a transition from higher orbit to lower orbit releasing a photon having energy which is equivalent to the energy difference between the two orbits.

A body has weight 600N on the surface of the mars then what is its mass on the same place.

laiz [17]

Answer:

$\boxed{m = 162.16 kg}$

Explanation:

Given:

Weight = W = 600 N

Acceleration due to gravity = g = 3.7 m/s²

Required:

Mass = m = ?

Formula:

W = mg

Solution:

For m, it'll be

=> m = W/g

=> m = 600/3.7

=> m = 162.16 kg
