True or False Questions, involving wires and currents

In the picture below, the two wires carry current i1 and i2, respectively, with positive current to the right. The charge q is positive and has velocity v to the right. 2 FalseIf i10 and i2 is greater than zero, then the force on q points out of the page. True If i20 and i1 is greater than zero, then the force on q is north True If i2 then the force on q equals zero. False If i 0 and i2 is greater than zero, then the magnetic field near charge q points into the page True If v 0, then the force on q is zero. True If i12, then the wires are attracted to each other True If i1 is less than i2, then the force on q is south..

Explanation / Answer

A) False ( it points northwards)

B) True ( net magnetic field is into the page and hence by fleming's left hand rule, the force is northwards on q)

C) False

( if i2 = -i1 , we have the net magnetic field into the page which gives a non zero force on q )

D) . False

( Use right hand palm rule, we get the magnetic field to be pointing out of the page)

E) True ( F= qvB , if v= 0 , then force =0)

F) True ( Using Fleming's left hand rule , clearly , the two wire s attract each other)

G) True ( net magnetic field is into the page and hence by fleming's left hand rule, the force is southwards on q)
