Total: 54

A small bob of mass 100 mg and charge +10µC is connected to an insulating string of length 1 m . It is brought near to an infinitely long non-conducting sheet of charge density ' σ ' as shown in figure. If string subtends and angle of 45∘ with the sheet at equilibrium the charge density of sheet will be.
