Expert Solution
Step 1

We are authorized to answer three subparts at a time, since you have not mentioned which part you are looking for, so we are answering the first three subparts, please repost your question separately for the remaining subpart.

Given

Length of bar L=12m=0.5 mB=5 Tmass m=2 kgbattery emf Ebat=103 VR=2 Ω

Step 2

For a bar moving in magnetic field, Force acting on bar is given as

                                                                                  F=BiL     ..........(1)where F=mai =ibat-iind   =EbatR-EindR  Ebat-EindRi =Ebat-BLvR

                                                                

 

Step 3

From equation 1

                                                                        ma=Ebat-BLvRBLa=dvdt=(Ebat-BLv)BLmRdv(Ebat-BLv)=BLmRdttaking intrgration0vdv(Ebat-BLv)=0tBLmRdt-ln (Ebat-BLv)BL0v =BLtmRlnEbatEbat-BLv=BLtmREbat-BLvEbat=e-B2L2tmRv=EbatBL(1-e-B2L2tmR)   expression for velocity ...(2)
