Consider two parallel, conducting frictionless tracks kept in a gravity-free space as shown in figure. A movable conductor PQ, initially kept at OA, is given a velocity 10 ms^-1 toward right. The space contains a magnetic field which depends upon the distance moved by conductor PQ from the line OA and given by

$\overrightarrow{\mathrm{B}}=\mathrm{cx}(-\hat{\mathrm{k}})[\mathrm{c}=\mathrm{constant}=1\text{ SI unit }]$

The mass of the conductor PQ is 1 kg and length of PQ is 1 m.
Answer the following questions based on the above passage.
