Question
One wire carries a current of 1 out of the plane of the page. The other carries a current 21 into the page. Wire 1 exerts a stronger force on II than II exerts on I. Wire 1 exerts a weaker force on II than II exerts on L The wires exert equal attractive forces on one another. The wires exert equal repulsive forces on one another. The wires exert no force on one another. When a magnet is hung by a string, it orients to the Earth's magnetic field where the magnet north pole points north towards a magnetic north pole of the earth. the magnet north pole points north towards a magnetic south pole of the earth. the magnet south pole points north towards a magnetic north pole of the earth. the magnet south pole points north towards a magnetic south pole of the earth. None of the above. The Pasco Scientific apparatus for measuring Coulomb's law is well designed. The charged object mounted on the torsion wire has a counter eight which passes between the poles of a magnet. This produces a rapid damping of any spatial oscillations of the charge by Coulomb's law Faraday's law Eddy Currents Ampere's law Cross currentsExplanation / Answer
13) option c. The force applied by first body on a second body is equal and opposite to the force applied by second on first. and since the currents are in opposite direction hence force would be attractive.
14) The magnet align itself in opposite direction of poles. Hence magnet's north points to magnetic south pole and vice-versa. option b and c are correct.
15) option b) Faraday's law states that a moving charged object in a magnetic fields is acted by a force equal to q(v X B) which dampens any spatial oscillations.
