A +6.33 uC charge q1 is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. What is the value of q2?

Answers

Answer:-4.1858

Explanation: I hate Acellus

If A +6.33 μC charge q₁ is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. then the value of q₂ = 4.23 μC.

What is coulomb's law ?

Electrostatic force is a force of attraction or repulsion between two unlike or like charges respectively. when like charges come closer to each other, they gets repel by one another and it gets attracted for unlike charges. Force of attraction or repulsion between two point charges are given by coulomb's law. The force of attraction between two charges are given by coulomb's law.

the law states that the force of attraction or repulsion between two point charges is directly proportional to product of magnitude of both the charge and inversely proportional to square of the distance between them.

i.e. F ∝ q₁q₂

F ∝ 1/r²

F ∝ q₁q₂/r²

F = kq₁q₂/r²

where k is proportionality constant k = 1/4π∈₀ = 8.9×10⁹

In this problem,

Given,

q₁ = 6.33×10⁻⁶ C

F = 0.115N

r = 1.44m

q₂ = ?

putting this values in the equation,

0.115 = 8.9×10⁹×6.33×10⁻⁶ ×q₂÷1.44²

q₂ = 4.23 μC.

A student charges a balloon and then brings it near a metal sphere hanging from the
ceiling. She brings it near the sphere, but does not touch. The sphere moves toward
the balloon. What are the charges on the balloon and the metal sphere?
a) The balloon has a positive charge and the metal sphere has a negative charge.
b) The balloon has a negative charge and the metal sphere has a positive charge.
c) Both are negatively charged.
d) Both are positively charged.

Answers

Answer:

Explanation:

the balloon has a negative charge and the metal sphere has a positive charge

Answer: B

Explanation:

The balloon will pick up stray electrons, so it will become negatively charged. Since it is attracted to the metal sphere, the sphere must be positively charged.

What is the rule you would write describing how light reflects off a mirror?

Answers

Answer: The angle of incidence equals the ray of reflection. So this law states that any ray of light that strikes an object will reflect off the object such that the striking or incident angle is identical to the reflecting angle (as measured from the normal).
