Answer:
1. (a)strongly attractive
2 (c) weakly attractive.
Step-by-step explanation:
Consider three plastic balls (A, B, and C), each carrying a uniformly distributed charge equal to either +Q, -Q or zero, and an uncharged copper ball (D). A positive test charge (T) experiences the forces shown in the figure when brought very near to the individual balls. The test charge T is strongly attracted to A, strongly repelled from B, weakly attracted to C, and strongly attracted to D.
should be the concluding part to this question as presented above
1. What is the nature of the force between balls A and B?
a) strongly attractive.
b) strongly repulsive.
c) weakly attractive.
d) neither attractive nor repulsive.
since there is an attractive force between ball A and the test charge, the charge on ball A must be negative
A = -Q
since ball B is repulsive to the test charged , then B must be positively charged
B = +Q
since A is negative and B is positive , then they will experienced a strong attraction
option A
2. What is the nature of the force between balls A and C?
a) strongly attractive.
b) strongly repulsive.
c) weakly attractive.
d) neither attractive nor repulsive .
Since C is weakly attracted to the test charge, we can say that Ball C will be weakly attracted to A, because it possess some weka charges
option C
