Two cars are travelling side by side down a straight road in the same direction. Both cars are travelling at a speed of 22m/s. W

ivann1987 [24]

Answer:

0 m/s

Explanation:

Relative speed is defined as the speed of an object with respect with another object.

In other words, it is the speed of an object as viewed from the frame of reference of another object.

When two objects are moving in the same direction, their relative velocity is given as:

$V_{12} = V_1 - V_2$

where $V_1 =$ velocity of first object

$V_2 =$ velocity of second object

In the case of the two cars, $V_1 =$ $V_2 =$ 22 m/s

Therefore:

$V_{12} = 22 - 22 = 0 m/s$

Their relative velocity is 0 m/s.

Two small identical metal spheres, A and B, on insulated stands, are each given a charge of +2.0 x 10-5 coulomb. The distance be

SpyIntel [72]

Answer:

a) 90 N

Explanation:

Coulomb's law: states that the electric force of attraction or repulsion between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

It is represented mathematically as

F = 1/4πε₀(q₁q₂)/d²......................... Equation 1

Where F = Electrostatic force, q₁ = charge on the first metal sphere, q₂ = charge on the second metal sphere, d = distance between the spheres, 1/4πε₀ = proportionality constant.

Given: q₁ = +2.0×10⁻⁵ C, q₂ = 2.0×10⁻⁵, d = 2.0×10⁻¹ m

Constant : 1/4πε₀ = 9×10⁹Nm²/C²

Substituting these values into equation 1,

F = (9×10⁹×2.0×10⁻⁵×2.0×10⁻⁵)/(2.0×10⁻¹)²

F = (9×4×10⁻¹)/4×10⁻²

F = 90 N

Therefore the electrostatic force is = 90 N

The right option is a) 90 N
