Two bar magnets placed together in a vibration magnetometer take 3 seconds for 1 vibration. If one magnet is reversed, the combination takes 4 seconds for 1 vibration. Find the ratio of their magnetic moments. |

Answer» Solution :GIVEN that,`T_1 = 3S and T_2 = 4s ` `(M_1)/(M_2) = (T_2^(2) + T_1^(2))/(T_2^(2)-T_1^(2))=(4^(2) + 3^(2))//(4^(2) - 3^(2)) = (16+9)/(16-9) = (25)/(7)` ` or (M_1)/(M_2)=3.57` |
