question 41

Multiple Choice

Two point charges of +2.00 μC and +4.00 μC are at the origin and at the point x = 0.000 m,y = -0.300 m,as shown in the figure.What is the electric potential due to these charges,relative to infinity,at the point P at x = 0.400 m on the x-axis? (k = 1/4πε₀ = 8.99 × 10⁹ N ∙ m²/C²)

• A)117 kV
• B)15.7 kV
• C)11.7 kV
• D)56.0 kV
• E)36.0 kV

Observational Learning

The process of acquiring new behaviors or knowledge by watching and imitating the actions of others, also known as social learning or modeling.

Model

In science and engineering, a model is an abstract representation meant to study, simulate, or explain the behavior of real systems or phenomena.

Discriminative Stimulus

A stimulus in the presence of which a particular response will be reinforced, used in behavioral psychology to study learning and conditioning.
