1.	A very long straight wire carries a current I. At the instant when a charge +Q at point P has velocity v, as shown, the force on the charge is?1) Opposite to OX2) Along OX3) Opposite to OY4) Along OY
Answer» Answer: F =q( V × B )=QVB( i ^ ×(− k ^ ))=qvB J ^ ⇒ force on the charge is along OY PLEASE mark as BRAINLIST answer and follow me please thank answer
