Final answer:
The true statements about permanent charging using induction include the charges on the balls and the effect of grounding.
Step-by-step explanation:
The true statement(s) regarding the permanent charging of an object using induction are:
- Ball 1 will have positive charge and Ball 2 will have negative charge.
- The negatively charged rod attracts the positive charge of Ball 1. The electrons of Ball 1 are transferred to Ball 2, making it negatively charged.
- If Ball 2 is grounded while the rod is still there, it will lose its negative charge to the ground.
- Yes, Ball 1 will be positively charged and Ball 2 will be negatively charged.
