1.	What is the net charge on a conducting sphere of radius 10cm?Given that the electric field 15 cm from the centre ofthe sphere is equal to3 x 103 N/C and is directed inward(1) -7.5 * 10-5C 1 -7.5 × 10-9 C(3) 7.5 × 10-5 C (4) 7.5 × 10-9 C
Answer» Answer: option 2 is correct EXPLANATION: electric field OUTSIDE CONDUCTOR is kQ/R^2 equate it with the electric field and find out q since electric field is directed INSIDE negative sign COMES
