Answer:
Ep = 3797.05 N/C in the direction leaving the charge q₂ towards point P
Explanation:
Conceptual analysis
The electric field at a point P due to a point charge is calculated as follows:
E = k*q/d²
E: Electric field in N/C
q: charge in Newtons (N)
k: electric constant in N*m²/C²
d: distance from charge q to point P in meters (m)
Data
k= 8.99*10⁹ N*m²/C²
q₁ = +13.6 x 10⁻⁹C
q₂ = +61.0*10⁻⁹C
d₁ =d₂= 33.5 cm = 0.335 m
Look at the attached graphic:
E₁: Electric Field at point P due to charge q₁. As the charge q₁ is positive (q₁+) ,the field leaves the charge
E₂: Electric Field at point P due to charge q₂. As the charge q₂ is positive (q₂+) ,the field leaves the charge
E₁ = k*q₁/d₁² = 8.99*10⁹ *13.6 *10⁻⁹/(0.335)² = 1089.45 N/C
E₂ = k*q₂/d₂²=- 8.99*10⁹ *61*10⁻⁹/(0.335)² = - 4886.5 N/C
Magnitude of the electric field at a point midway between q₁ and q₂
Ep= - 4886.5+ 1089.45 = -3797.05 N/C
Ep = 3797.5 N/C in the direction leaving the charge q₂ towards point P
The correct answer to the question is- C).Electrons are ripped off one material and held tightly by the other material.
EXPLANATION:
Before going to answer this question, first we have to understand the charging by friction.
There are three modes of charging a body, which are known as friction,conduction, and induction.
Friction: Friction is the type of charging a body due to the actual transfer of electrons when two substances of different electron affinities are rubbed with each other. During rubbing, the electrons from less electron affinity substance will be transferred to high affinity substance.
The substance which will accept electrons gets negatively charged, and the other substance will be positively charged.
There will be no transfer of protons from one substance to another as protons are bound inside the nuclei of atoms.
Hence, the correct answer to the question is that electrons are ripped off one material and held tightly by the other material.
Answer:
it relates to the economic in these ways
1.unlimited resources
2 wants
Explanation:
human being want resources to provide good and services to satisfy human wants
wants are insatiable desire
