Electricity
FREE SOLUTION - In Figure, determine the point (other than infinity) at which the total electric field is zero.
In Figure, determine the point (other than infinity) at which the total electric field is zero.
Now, write the electric field for each particle:
equating electric field expressions to zero and solve for X:
minus sign present in our answer says that this distance is to left of -2.5x10^(-6) C charge. So the correct answer is : 1.82 m to the left of the -2.5x10^(-6) C charge
Determine the point at which the electric field is zero
Here, we have a problem on electricity that is to usual on test and homework. For solve this problem we need understood only one thing what signify total electric field is zero?. Well ... it's too easy answer this! signify that the sum of two electric field is equal to zero... in words, we write the electric field for both electric charge and then sum his expressions equating to zero. redraw the problem for show the distance needed to have total electric field equal to zero:Now, write the electric field for each particle:
equating electric field expressions to zero and solve for X:
Zero electric field
minus sign present in our answer says that this distance is to left of -2.5x10^(-6) C charge. So the correct answer is : 1.82 m to the left of the -2.5x10^(-6) C charge
