and... please tell methe rules too... D: the direction is confusing
I don't understand those symbols :O
shininigami electric field 's direction is away from a positive charge, and towards a negative charge.
this is the case if BOTH CHARGES ARE POSITIVE.. and their magnitudes almost same..
but my answer key says like this....
yeah, it's because we have to show only the horizontal field, all are positive, and if q2>q>q1, then this will be the answer
is it from left to right or it should be from largest to biggest??
sorry.. direction of electric field on Q? :D!!.. i just drew lines of force!!..
|dw:1329406488894:dw|see from a positive charge field should originate if there are two positive charges in a line, then charge will originate from both, here q2 and q1 are positive
|dw:1329406677857:dw|if q2> q1 => field due to q2 (E2) > field due to q1 (E1) so in between them, the fields are opposite effective field between them = E2- E1 int he direction shown
i think i;m getting this... hahah since q is only a test charge... i think i can deny its quantity
actually your question doesn't make sense.. direction of electric field ON q!??!?!? ..
