A learner in Physical Sciences class rubs his hair with a plastic rod. The rod becomes negaively charged. The learner now opens a tap so that thin stream water runs from it. When the rod is brought close to the water without touching it, it is cbserved that the water bends towards the rod. 9.1 Give a reason why the stream of water bends towards the rod. 9.2 Two small metal spheres, on insulated stands, carry charges of -3 x 10-6C and and then returned to their original positions. +6 x 10-6C respectively. The spheres were moved to touch one another, got separated R. R x 10 C +6 x 10 C Stage 1 Stage 2 Stage 3 IT IT TT- 9.2.1 Which one of the twe spheres, P or R, at Stage1, has an electron deficiency? 9.2.2 Will the spheres at Stage 3 Attract or Repel?

ClossworK 90 QUESTION 9 A learner in Physical Sciences class rubs his hair with a plastic rod. The rod becomes negatively charged. The learner now opens a tap so that thin stream water runs from it. When the rod is brought close to the water without touching it, it is cbserved that the water bends towards the rod. 9.1 Give a reason why the stream of water bends towards the rod. 9.2 Two small metal spheres, on insulated stands, carry charges of -3 x 10-6C and +6 x 10-6C respectively. The spheres were moved to touch one another, got separated and then returned to their original positions. P. R. R. P.
