Abattery is used to charge a parallel combination of two identical capacitors. if the potential difference across the battery terminals is v and total charge q flows through the battery during the charging process then the charge on the positive plate of each capacitor and the potential difference across each capacitor are

Unpolarized light of intensity so passes through two sheets of polarizing material whose transmission axes make an angle of 60∘ with each other as shown in the figure. what is the intensity of the transmitted beam, st?
