"two long parallel wires 24.0 cm apart carry currents of 3.0 a and 8.0 a in the same direction. how far from the wire carrying 3.0 a is the magnetic field is zero (in cm)? "

6.5454 m

Explanation:

Let the distance from the wire carrying 3 A current is x

Then the distance from the the carrying current 8 A is 24-x

We know that magnetic field due to long wire is given by

It is given that magnetic field is zero at some distance so

Here

So

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333
