Question 9 and 8 thanks

Two identical conducting balls, b, and b2, each of mass 25.0 g, are hanging on 50.0 cm long insulating threads. They become equally charged and come to rest with angles of deviation of 45.0" from the vertical. 50.0 cm 50.0 cm 45 1 45 8. What is the tension in the thread that is supporting one of the balls? 9.81 N 0.173 N 0.347 N 0 0.245 N 9. If the charge on b, is tripled and the charge on by is reduced to one-third of its original amount, the angles of deviation from centre would: increase for both b, and b2 O remain the same for both b, and b2 ") increase for by and decrease for b2 " decrease for both by and b2
