This question is about the velocity selector shown in figure. Explain why ions travelling with a speed greater than your answer to part (b) will not emerge from the slit.

Magnetic force is greater than electric force. So, the ion travels in an upward curved path (towards the positive plate) and hence misses the slit S.
