Q: In a photoelectric experiment, if the stopping potential is increased, what does it indicate about the emitted electrons?

Solution: Increasing the stopping potential indicates that the emitted electrons have higher kinetic energy, as more energy is required to stop them.

Steps: 5

Step 1: Understand what stopping potential means. It is the voltage needed to stop emitted electrons from reaching the detector.
Step 2: Know that emitted electrons come from a material when light hits it in a photoelectric experiment.
Step 3: Realize that when light hits the material, it gives energy to the electrons, allowing them to escape.
Step 4: If the stopping potential is increased, it means that the electrons are moving faster and have more energy.
Step 5: Conclude that a higher stopping potential indicates that the emitted electrons have higher kinetic energy.
