Three straight parallel current carrying conductors are shown in the figure. The force experienced by the middle conductor of length 25 cm is :
3 x 10-4 N toward right
6 x 10-4 N toward left
9 x 10-4 N toward left
Zero
As we have learned
Force between two parallel current carrying conductors -
- wherein
I1 and I2 current carrying two parallel wires
a-seperation between two wires
Force due to wire I
towards right
Force due to wire two
towards left
Net force =
Option 1)
3 x 10-4 N toward right
Option 2)
6 x 10-4 N toward left
Option 3)
9 x 10-4 N toward left
Option 4)
Zero
