Ops: A. Oa
B. Ob

Answer 1

Answer:

arrangement in a straight line or in correct relative positions.

"the tiles had slipped out of alignment"

2.

a position of agreement or alliance.

"the uncertain nature of political alignments"

Answer 2

Answer:

The correct answer is d) As r → 00, U=0

Explanation:

The electrostatic force is a conservative pressure i.e., the total strength of the gadget (capability electricity + kinetic power) remains same and it act within the path of reducing the potential strength.

So, while  in contrast to fees get nearer due to electrostatic force of enchantment, the capability electricity decreases.

as a consequence, both assertion and motive are authentic and cause is correct clarification of the assertion. notice that the electrical capability power is fantastic if the 2 fees are of the same kind, both wonderful or terrible, and bad if the 2 costs are of opposite types. This makes sense if you consider the exchange within the capacity electricity ΔU as you carry the two prices nearer or pass them farther aside. the electric capacity is zero at an infinite distance from the factor charge. for two contrary costs of identical importance, the electric potential is zero within the middle because the electric powered area between each the costs could be identical and contrary.
