Two point charges are located on the x-axis of a coordinate system; q1 = 2 nc is at x = 1 cm, and q2 = -4 nc is at x = 3 cm. what is the total electric force exerted by q1 and q2 on a charge q3 = 5 nc at origin?

The total electric force exerted by q₁ and q₂ on a charge q₃ is

Explanation:

Given that,

First charge

Distance = 1 xm

Second charge  

Distance = 3 cm

Charge at origin

We need to calculate the total electric force exerted by q₁ and q₂ on a charge q₃

For first force,

Using formula of electric force

Put the value into the formula

For second force,

Using formula of electric force

Put the value into the formula

The total electric force is

Hence, The total electric force exerted by q₁ and q₂ on a charge q₃ is

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
