Two identical pith balls, each carrying charge q, are suspended from a common point by two strings of equal length l. Find the mass of each ball if the angle between the strings is 2theta in equilibrium.

Two identical pith balls, each carrying charge q, are suspended from a common point by two strings of equal length l. Find the mass of each ball if the angle between the strings is 2theta in equilibrium.

Two indentical pith balls, each carrying charge q, are suspended from a common point by two strings of equal length l. Find the mass of each ball if the angle between the strings is 2theta in equilibrium.

Two indentical pith balls, each carrying charge q, are suspended from a common point by two strings of equal length l. Find the mass of each ball if the angle between the strings is 2theta in equilibrium.

Two path balls carrying equal charges are suspended from a common point by strings of equal length, the strings are rightly clamped at half the height. The equilibrium separation between the balls, now becomes :

Two small balls, each having equal positive charge Q are suspended by two insulationg strings of equal length l from a hook fixed to a stand. It mass of each ball =m and total angle between the two strings is 60^(@) m, then find the charge on each ball.

Two small balls, each having equal positive charge Q are suspended by two insulationg strings of equal length l from a hook fixed to a stand. It mass of each ball =m and total angle between the two strings is 60^(@) m, then find the charge on each ball.

Two pith balls carrying equal charges are suspended from a common point by strings of equal length, the equilibrium separation between them is r.Now the strings are rigidly clamped at half the height.The equilibrium separation between the balls now become:
