(Multiple choice)

If a negatively charged plastic rod is brought near a copper sphere that is grounded, and then the ground is removed, what will the charge of the copper sphere be when plastic rod is removed? (explain why that answer is correct)

a. electrically neutral

b. positively charged

c. negatively charged

check_circleExpert Solution
Step 1

When negatively charged plastic rod is brought near the copper sphere, positive charge will be induced on the sphere because of electrostatic induction.

Step 2

When ground is removed before removing the rod, sphere will be positively charged. This is because when the rod is removed, the ind...
