Question 1 of 10

Question 2 of 10

2. A capacitor is charged with a battery and then it is disconnected. A slab of dielectric is now inserted between the plates, then:

1.The charge in the plates reduces and potential difference increase

2.Potential difference between the plates decreases, stored energy decreases and charge remains the same

3.Potential difference between the plates decreases, stored energy decreases and charge remains unchanged

4.Potential difference between the plates increase, stored energy decreases and charge remains the same
