Two small spherical balls each carrying a charge math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymi mathvariant=normalQ/mimo=/mo/mathmath xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymn10/mnmiμC/mi/math (10 micro-coulomb) are suspended by two insulating threads of equal lengths math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymn1/mnmo /momi mathvariant=normalm/mi/math each, from a point fixed in the ceiling. It is found that in equilibrium threads are separated by an angle math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymn60/mnmo°/mo/math between them, as shown in the figure. What is the tension in the threads?
