A pith ball carrying a charge of `3 xx 10^(-10) C` is suspended by an insulated thread of length `50 cm`.When a uniform electric filed is applied in a horizontal direction , the ball is found to deflect by `2 cm` from the vertical. If the mass of the ball is `0.5 gm` , the intensity of the electric field is :

A charged particle of mass 1 g is suspended through a silk thread of length 40 cm in a horizontal electric field.fo 4.0 xx 10^4NC^-1 . If the particle stays at a distane of 24 cm from the wall in equilirbium, find the charge on the particle.

Two small spherical balls each carrying a charge Q= 10 mu C ( 10 micro=coulomb) are suspended by two insulating threads of equal lengths 1 cm each, from a point fixed in the ceiling. It is found that in equilibrium threads are sepreated by an angle 60^(@) between them, as shown in figure. What is the tension in the threads (Given (1)/(4piepsilon_(0))= 9xx10^(9)Nm//C^(2) )

A 0.50 gm ball carries a charge of magnitude 10mu C . It is suspended by a string in a downward electric field of intensity 300N/C. If the charge on the ball is positive, then the tension in the string is (g = 10 ms^(-2))

A "0.50gm" ball carries a charge of magnitude 10 mu C" It is suspended by a string in a downward electric field of intensity "300N/C" .If the charge on the ball is positive,then the tension in the string is g=10ms^(-2)
