Answer:

Force on Sphere A due to B = F

Explanation:

The electrostatic force between the two charges is given by the Coulomb's Law, by the following formula:

F₁₂ = kq₁q₂/r²

where,

F₁₂ = Force on charge 1 due to charge 2

k = Coulomb's Constant

q₁ = magnitude of charge 1

q₂ = magnitude of charge 2

r = distance between both the charges

Similarly, the force on charge 2 due to charge 1 is given by the following formula:

F₂₁ = kq₁q₂/r²

It is clear from the formula that the force of both the charges on each other due to the other charge are same. Therefore, in our case:

Force on Sphere A due to B = Force on Sphere B due to A

<u>Force on Sphere A due to B = F</u>

The main advantage banking services offer is?
KATRIN_1 [288]
In short, and in general:

Advantages

<span>Credit Unions typically pay higher dividend rates on savingsCredit Unions typically offer lower rates on loansCredit Unions typically provide better service; since they are owned and governed by their membership, they tend to prioritize the needs of their members above all elseCredit Unions operate on a not-for-profit business model, so excess earnings are returned back to the membership in form of competitive rates and lower fees, and sometimes even special dividendsMany Credit Unions offer the same products and services found at banksCredit Unions often have added-value benefits, such as free financial education, discounted theme park tickets, and special member rates for services such as home alarm systems...even discounts at online retailers like Barnes & Noble.</span>Disadvantages

<span>Credit Unions, and in particular smaller local credit unions, struggle to match the level of convenience (ATMs and branches) that many banks provide their customers, although many CUs are part of shared networks which enhance the breadth of delivery channels available to their membersSome Credit Unions are limited in their product offeringsOne must qualify for membership <span>One must pay a membership fee to join. hope this helps!
