Answer : Smaller than 9.8 m/s2
As the bar magnet moves into the wire, because of the flux change current will induce in the wire. This induced current will appose the magnet. Thus, acceleration of the magnet will decrease by some amount and it will be lesser than 9.8 m/s2

Q4 A bar magnet is held above a loop of wire in a horizontal plane, as shown in Figure. According to the Lenz's law (write the Lenz's law), find the direction of the induced current through the resistor (a) while the magnet is falling toward the loop and (b) after the magnet has passed through the loop and moves away from it (draw the magnetic field lines of both the magnet and loop).

Two equally charged particles, held 3.6 × 10-3 m apart, are released from rest. The initial acceleration of the first particle is observed to be 9.6 m/s2 and that of the second to be 13 m/s2. If the mass of the first particle is 6.8 × 10-7 kg, what are (a) the mass of the second particle and (b) the magnitude of the charge of each particle?

A rectangular loop of wire with dimensions and w is released from rest at time t = 0 from a region with zero magnetic field into a region with uniform magnetic field Bo pointing into the page. At t=0, the upper edge of the loop is in the zero field region and the lower edge is in the uniform field region as shown in the figure below. The loop has mass m and the acceleration due to gravity is g...
