When a resistance of $100 \Omega$ is connected in series with a galvanometer of resistance ' G ', its range is ' $V$ '. To double its range, a resistance of $1000 \Omega$ is connected in series. The value of ' $G$ ' is

Light of incident frequency 3 times the threshold frequency is incident on a photosensitive material. If the incident frequency is made $\left(\frac{1}{4}\right)^{\text {th }}$ and intensity is tripled then the photoelectric current will
