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

Step-by-step 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
