Answer:
Option D, The claims may be biased, is the right answer.
Explanation:
Option D is the correct answer because the primary motive of a company is to earn more profit and it can misguide the consumer by making false and biased claims. Therefore, the evaluation of the claims is the responsibility of the buyers which help them to buy the product beneficial to them. For example, if a product claims that it will glow your skin within seconds then it is the awareness or activeness of the consumer to evaluate such claims which are written on the label and cross verify the ingredients that are used in it because such claims can be false to sell the product.

Answer:
The absolute potential 4.0 m away from the same point charge is -50 V.
(A) is correct option.
Explanation:
Given that,
Distance = 2.0 m
Potential = -100 V
Absolute potential = 4.0 m
We need to calculate the charge
Using formula of potential

Where, V = potential
q = charge
r = distance
Put the value into the formula



We need to calculate the potential
Using formula of potential



Hence, The absolute potential 4.0 m away from the same point charge is -50 V.
