a charged particle moves in a gravity-free space without change in velocity.which of the following is/are possible? (A)E=0,B=0 (B)E=0,Bnot=O (C)Enot=0,B=0 (D)Enot=0,Bnot=0

Salim Shamim · Answer

Freind :)

Answer must be A.

Explaination:

As its moving with constant velocity it must not be experiencing any force as accelaration is =0. Therefore no Electric force hence no electric field is present there, also there is no magnetic field as a charge moves in circular path which is also a type of acceleration and causes change in velocity vector,
therefore E=0 and also B=0. :)

Ramit Hansda · Answer

Option C is correct qvB=Ee ,so B=0 E =0 is possible E not equal to zero B not equal to zero is possible If it is a circular motion velocity uniform E=0 but B not 0 is possible. ..
