A+1.0 c charged object and a +2.0 c charged object are separated by 100 m. where should a -1.0x10-3 c charged object be placed on a line between the positively charged objects so that the net electrical force exerted on the negatively charged object is zero?

The negative charge should be placed 41 m from +1.0 C charged object

Electric charge consists of two types i.e. positively electric charge and negatively electric charge.

There was a famous scientist who investigated about this charges. His name is Coulomb and succeeded in formulating the force of attraction or repulsion between two charges i.e. :

F = electric force (N)

k = electric constant (N m² / C²)

q = electric charge (C)

r = distance between charges (m)

The value of k in a vacuum = 9 x 10⁹ (N m² / C²)

Let's tackle the problem now !

Given:

Q₁ = +1.0 C

Q₂ = +2.0 C

R₁ = x

R₂ = 100 - x

q = -1.0 × 10⁻³ C

Unknown:

x = ?

Solution:

In order to produce a total force = 0, the electric forces acting on this negative charge must be in the opposite direction and equal in magnitude.

We assume the distance of this negative charge to the positive charge +1.0 C is x, then:

attach the statements so i can answer : )

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
