Answer 1

The object A is a most likely conductor because field lines are not penetrating it.

(061)

Since the charge strength is proportional to the number of field lines starting/ending to the charged particle hence

for $q_1$ , number of field lines are 11 while for $q_2$ , it is 4 hence

$\frac{q_1}{q_2}=\frac{11}{-4}=-2.75$

-ve sign because field line goes into the charge $q_2$ which shows that it is negatively charged.

(062) Potential is largest at point 3

(063) The field is directed from left to right and negatively charged particle always moves opposite to the field line hence it will accelerate towards left

(064) The field is smallest at point 1 because here the field density is minimum

(065) Both point will have same potential bec they are the part of same body.
