of I pt A proton is moving diagonally inside a region where there is a horizontal electric and a vertical magnetic field as shown in the figure. Select True or False for the following statements. D The electric force on the proton points up 26. AO Tr BO False D The magnetic force on the proton points down 27. AO True BO False D If the speed of the proton is doubled, then the magnitude of the electric force halves 28. AO True Bo False
Solution
26) electric force in the proton will be in the direction of electric field so electric force points right.
So it\'s false.
27) magnetic force on the proton will be perpendicular to the velocity as well as magnetic field so magnetic force will be out of the plane.
So it\'s also false.
28) electric force (F) = qE
It doesn\'t depend upon the speed so it\'s also false.

1. of I pt A proton is moving diagonally inside a region where there is a horizontal electric and a
vertical magnetic field as shown in the figure. Select True or False for the following statements.
D The electric force on the proton points up 26. AO Tr BO False D The magnetic force on the
proton points down 27. AO True BO False D If the speed of the proton is doubled, then the
magnitude of the electric force halves 28. AO True Bo False
Solution
26) electric force in the proton will be in the direction of electric field so electric force points
right.
So it's false.
27) magnetic force on the proton will be perpendicular to the velocity as well as magnetic field
so magnetic force will be out of the plane.
So it's also false.
28) electric force (F) = qE
It doesn't depend upon the speed so it's also false.
