28 A thin strip 10 cm long is on a U shaped wire of negligible resistance and it is connected to a spring of spring constant 0 5 Nm see figure The assembly is kept in a uniform magnetic field of 0 1 T If the strip is pulled from its equilibrium position and released the number of oscillation it performs before its amplitude decreases by a factor of e is N If the mass of the strip is 50 grams its resistance 102 and air drag negligible N will be close to 8 April 2019 Morning
