Two parallel conductors `A` and `B` of equal lengths carry currents `I` and `10 I`, respectively, in the same direction. Then

A, B and C are parallel conductors of equal length carrying currents I, I and 2I respectively. Distance between A and B is x . Distance between B and C is also x . F_(1) is the force exerted by B on A and F_(2) is the force exerted by B on C choose the correct answer

A, B and C are parallel conductors of equal length carrying currents I, I and 2I respectively. Distance between A and B is x . Distance between B and C is also x . F_(1) is the force exerted by B on A and F_(2) is the force exerted by B on A choose the correct answer

A, B and C are parallel conductors of equal length carrying currents I , I and 2I respectively. Distance between A and B is x . Distance between B and C is also x . F_1 is the force exerted by B on A. F_2 is the force exerted by C on A. Choose the correct answer.

Two parallel conductors A and B separated by 5cm carry electric current of 6A and 2A in the same direction. The point between A and B where the field is zero at

Two long straight parallel conductors 10 cm apart, carry equal currents of magnitude 3A in the same direction. Then the magnetic induction at a point midway between then is

Two long straight thin conductors carrying currents I_1 and I_2 respectively along the same direction are placed parallel to each other in air. Derive an expression for the force per unit length acting on any one of the conductors and hence define one ampere current.
