A charged object is brought near a neutral object. They will: (A) Attract if charged object is positively charged; repel if negatively charged.(B) Repel Sometimes attract, sometimes repel (C) Repel if charged object is positively charged; attract if negatively charged.

(B) Sometimes attract, sometimes repel

Explanation:

When a charged object is brought near a neutral object causes a redistribution of the charges in the second object, due to the repulsion generated by the charges of the first object. In this process, the initial net charge has not changed in the neutral object, but in some areas it is positively charged and in the others is negatively charged. Therefore, regardless of the sign of the charge of the charged object, these objects will sometimes attract and sometimes repel.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
