The moment of inertia of thin square plate ABCD of uniform thickness about an axis passing through the center O and perpendicular to the plane of the plate is ( i ) I_(1)+I_(2) ( ii ) I_(2)+I_(4) ( iii ) I_(1)+I_(3) ( iv ) I_(1)+I_(2)+I_(3)+I_(4) where I_(1) , I_(2) , I_(3) and I_(4) are repectively moments of inertia about axes 1 , 2 , 3 and 4 which are in the plane of the plane

In the following circuit find I_(1) and I_(2)

Two long straight parallel wires carry currents I1 and I2 respectively, in the same direction (as shown). The distance between the wires is R. The magnetic field at the centre of the two wires will (1) (mu_(0)(I_(1)-I_(2)))/(piR) into the plane of paper (If I_(1) gt I_(2) ) (2) (mu_(0)(I_(2)-I_(1)))/(piR) out of the plane of paper (if I_(2) gt I_(1) ) (3) (mu_(0)(I_(1)-I_(2)))/(piR^(2)) out of the plane of paper (if I_(2) gt I_(1) ) (4) (mu_(0)(I_(2)-I_(1)))/(piR^(2)) into the plane of paper (if I_(1) gt I_(2) )

Two parallel long wires carry currents i_(1) and i_(2) with i_(1) gt i_(2) .When the current are in the same direction, the magnetic field at a point midway between the wire is 20muT .If the direction of i_(1) ,is reversed.the field becomes 30muT .The ratio i_(1)//i_(2) is

In the following circuit I_(1) and I_(2) are respectively
