9. A rectangular conducting loop of length 4 cm and width 2 cm is in the xy-plane, as shown in the figure. It is being moved away from a thin and long conducting wire along the direction + with a constant speed v. 3 1 2 2 The wire is carrying a steady current /= 10 A in the positive x-direction. A current of 10 A flows through the loop when it is at a distance d = 4 cm from the wire. If the resistance of the loop is 0.1 Q, then the value of vis ms [Given: The permeability of free space = 4 107 NA-] 4 cm 2 cm d / = 10 A y Lxx 10. A string of length 1 m and mass 2 105 kg is under tension T. When the string vibrates, two successive harmonics are found to occur at frequencies 750 Hz and 1000 Hz. The value of tension T is. newton.
