THank you Mark44,for helping me to reach to the answer.You made me think,which i already knew

the bigger radius becomes twice the smaller radius ie 2 mm.But what about the charge ?

i hope it adds up linearliy,that means ,radius of larger frop =8* 1mm (radius of each smaller drop)

I assume the volume to be (4/3)*(pi)*r^3,where r is 1 mm. But what potential has to do with Volume.i am quit weak in this subject

Homework Statement 8 Charged drops of water each of radius 1 mm and having a charge of 10^(-10) Coloumbs are combined to form a bigger drop.Determine the potential of the bigger drop. Homework Equations Does the radius becomes 4*10^(-3)m,when it combines? Does the charge sum up to...

so,does it require to take both the cases(along x-axis and y-axis)individually and finally add them ?? If that is the method,we will get an expression of function of x and y(instead of a constant value) right?

ok,but I am trying to do without the help of Gauss law..

Homework Statement Infinite uniform line charges of 5nc/m lie along the (positive and negative) x and y axes in free space. Find E at :P(0,3,4) Homework Equations E due to line charge along the Z-axis is given by: E=(λ/(2∏*ε*r))*ar where λ=line charge density;ε=...

oh,i got wrong with the midpoint formula..so now the midpoint is (1,1.5,3.5).is it correct??

Homework Statement *)Given two points A=(4,3,2) and B=(-2,0,5).Find the unit vector extending from origin toward the midpoint of line AB Homework Equations The Attempt at a Solution Direction vector to AB=(-6,-3,3) and hence direction vector to its midpoint is (-3,-1.5,1.5)...

ok ,thank you for the reply...what made me ask this question is-i saw maxwells equations(electromagnetic) written in phasor form from dpoint form by just substituting d/dt with jw..So what my questin is ,what is the implication of removing that time factor from that equation??

Why do we use phasor representation in physics..For example,why we need maxwells equation in phasor form as well??
