+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.directions of force you understood?
in second example i dont know why the vectors are pointing towards the sides
they should be pointing towards the charges
but anyway
i)
distance is same for all 4 charges = r/sqrt(2) (consider it to be
d)
the values of all the forces are F = KQq / d^2, they're all equal
and the forces cancel each other out
ii)
its an equilateral triangle so all the forces through the center are at an angle 120 degree from each other
and they're all equal (distance between the center charge and any of the 3 charges are the same)
so cancels out
if you're unfamiliar with that 120 degree result j try taking horizontal and vertical components and you'll see
Also because of symmetry, force will be zero in both.
I think my problem lies in this
u cn try to do once by taking the vector components nd it will all solve out to give zero
thts how this que gives zero
Yeah did it
