Activity 3: Electric Potential Demonstration Showing potential energy differences for the earth's gravitational field can be shown visually. Showing electrical potential (energy) difference is harder to visually show and understand. Use the gravity analogy to establish the electrical potential difference concept. (a) Drop an object (ex: baseball) from rest from 20 cm above a pie tin on spacers. Observe. (b) Reposition the pie tin and spacers to a different location and again drop the ball from 20 cm. Observe. (c) Drop the same ball onto pie tin 2, but from 100 cm above pie tin 2 and observe. Guide Questions: 1. Compare the noise created by the object dropped from 20 cm above and the created after the pie tin repositioned. 2. Compare the noise created by the object dropped from 20 cm above the pie tin and the object dropped from 100 cm above the pie tin. 3. What is the GPE difference (4U) of the object dropped at two different distances from the pie tin? 4. What does the sound created by the object in situation number 1 indicate?Problem Solving. Write complete solution at the back ( 10 points ) If the sphere on the right has a radius of 0.5m, 1.) What will be the magnitude of electric flux due O + 1:09 DC to enclosed charges of positive 1 nano coulomb and negative 3 nano coulomb? (3points) O -3.00 nC 2.) Will the flux increase or decrease if the radius was doubled? Why? (3 points) 3.Calculate the electric flux on the plane surface area. (might look simple but tricky, - 4 points) 15 cm x 15 cm 30 180 N/C
