Question

Question 1 Balls 1, 2, 3, and 4 are hanging by strings. A plastic rod, which has been rubbed with wool, is used to touch Ball 1. When the balls are brought near each other, but not touching, the following is observed Ball 2 is attracted to ball 3 . Balls 2 and 4 do not affect one another Balls 2, 3, and 4 are attracted to ball 1 What is ball 4's charge state? O Neutral Glass O Plastic Question 2 The leaves of an electroscope that is negatively charged are separated. What will happen to the separation between the leaves if you brought a negatively charged rod near, but without touching, the top of the electroscope? O It will remain the same. O It will become smaller It will become larger Question 3 Touch In the figure, metal sphere A has 4 negative charge units and metal sphere B has 2 positive charge units. What is the charge state of the spheres after you touch them together? Sphere A has -2 charge and sphere B has 0 charge O Sphere A and sphere B each have -1 charge. O Sphere A has +2 charge and sphere B has -4 charge. O Sphere A and sphere B each have -2 charge Question 4 Two charged spheres are placed as shown above. The size of the sphere represents how much charge it has. Choose the position (indicated by A, B, C, or D) where there would be zero net force on an electron.

Explanation / Answer


Question 1)

plastic rod attains positive charge and wool will attain negative charge due to friction

when plastic rod touches the ball 1 ,the ball 1 will get negative charges and ball 2 will get positive charge,ball 3 will get negative charge and ball4 will get positive charge due to induction

so the correct answer was ball 2 is attracted to ball 3

ball 4's charge state was plastic
