Two identical bar magnets are fixed with their centres at a distance d apart. A stationary charge Q is placed at P in between the gap of the two magnets at a distance D from the centre O as shown in the Figure

The force on the charge Q is 

  • Option 1)

    Direct prependicular to the plane of paper

  • Option 2)

    Zero

  • Option 3)

    Directed along OP

  • Option 4)

    Directed along PO

Magnetic force If B=0 -

F=qVBsin 	heta

F=0

-

 

 magnetic field apply force on moving charge only. Hence there is no force here on stationary charge 


Option 1)

Direct prependicular to the plane of paper

This solution is incorrect 

Option 2)

Zero

This solution is correct 

Option 3)

Directed along OP

This solution is incorrect 

Option 4)

Directed along PO

This solution is incorrect
