Answer 1

(a)

False.

True. Since, Q1 and Q3 are positive and Q2 is negative and if Q3 is larger than Q1, Q2 might feel a net force to the right.

True. Since Q1 and Q2 are negative, Q1 will repel Q2 to the right and Q3 being positive, Q2 will be attracted to Q3 ie, Q2 will feel a net force to the right.

False. Since Q2 and Q3 are negative they will repel each other and Q2 will move slightly to left and Q1 being positive, Q1 and Q2 will be attracted and ultimately Q2 will feel a neer force to the left. So the statement is false.
