Question

If in triangle ABC , the Euler line is parallel to BC , show that tanB.tanC=3​

Answer 1

Step-by-step explanation:

A capacitor having capacitance 10μF and potential 100 volt, another uncharged capacitor is

connected in parallel with it so that it's potential reduces to 40 volt. Then calculate the capacitance of the

second capacitor and loss ocapacitor of capacitance C is charged by a battery of P.D. V1 . Energy stored by the capacitor is E1 . The battery is then removed, and an identical uncharged capacitor is connected across the first capacitor. Energy stored by any one capacitor now is E2 . Find E1 : E2 .
