A rectangular loop with a sliding conductor of length $0.5 \text{ m}$ is located into a uniform magnetic field $B = 0.5 T$ perpendicular to the plane of loop. The part $AD$ and $BC$ has electrical resistance $R_1 = 50 \Omega$ and $R_2 = 50\Omega$ , respectively. The conductor of mass $M = 1\text{ kg}$ starts moving with constant acceleration $a_0 = 1\text{ m/s}^2$ . Neglecting the self inductance of the loop and resistance of conductor, the external force required to move the conductor with given acceleration after $n$ seconds of start is $1.01 \text { N}$ . What is the value of $n$ ?
