"K+" is the one metal ion among the choices given in the question that produces <span>the light with the highest energy. The correct option among all the options that are given in the question is the third option or the penultimate option. I hope that the answer has actually come to your help.</span>
B. accelerates in the direction of the force. this is because the force is now unbalanced, causing the object to move in that direction. it's like pushing a pen off the table. you applied force in that direction and since the pen doesn't have enough inertia to withstand your unbalanced force, it rolls off the table.
Force on a moving charge is given by formula

here we know that this force will be maximum when velocity is perpendicular to magnetic field

here we know that



now we have


Answer:
There are no gaps in space between the photons as they travel. If you were to look at a wave then you'd come to a conclusion that indeed that there aren't any gaps unless they are specifically placed.The light from a distance star indeed spreads out and weakens as it travels, but this just reduces the wave strength and does not introduce gaps.
