Question

A metal sphere A has charge 2. Two other spheres. B and C are identical to A except they have terone charge the theatret spheres are separated. After that B touches C, then the two spheres are separated. How much charge is on each sphere QA - 14. 08 - Q. Qc - / QA - 20 / 08 - 20 Oc= 20 QA=0.08-0. Oc=0 - 0, 0-8.0-9

Answer 1

А MS metal sphere is of charge toa brought in Contact with Sphere B which neutral initially. They are identical. are brought in Contact, then they reach in same potential. potential is so, when two spheres Let the Common let res after contact, the charge both spheries are 82 'శ్రీం on B1 and so +32 28. and 31 B2 B,+82 As they are identical they have same capacitance ze BL 28 xe - 28/2 ze 8 and 32=0 so Sphere A has charge a and sphere B has charge 8. is brought in contact then charge of sphere B Now, if Spherce with sphere B, is divided equally. Sphere Sphere c will has charge will has charge 812 and 8/2 so final is charge Res 8972 SA o be $12,
