Q9 of 92 Page 248

Two particles X and Y having equal charge, after being accelerated through the same potential difference enter a region of uniform magnetic field and describe circular paths of radii R1 and R2 respectively. The ratio of the mass of X to that of Y is

let the charge of both of them be q and mass be mx and my respectively. If they are driven through the same potential V then,


 


Thus, vx and vy (their respective velocities after leaving the potential) will be and


So from we get, (all the other terms are constant for both the particles)


So, according to the question


Thus,

Two parallel wires carry currents of 20 A and 40 A in opposite directions. Another wire carrying a current antiparallel to 20 A is placed midway between the two wires. The magnetic force on its will be

Two parallel, long wires carry currents i1 and i2 with i1> i2. When the currents are in the same direction, the magnetic field at a point midway between the wires is 10 μT. If the direction of i2 is reversed, the field becomes 30 μT. The ratio i1/i2 is
