Find a Mathematical Model for the Verbal Statement: the Force $F$

question 56

Multiple Choice

Find a mathematical model for the verbal statement: The force of attraction $F$ between two oppositely charged particles varies directly as the product of the magnitudes $Q _ { 1 }$ and $Q _ { 2 }$ of the charges and inversely as the square of the distance $d$ between the particles."

• A)\(B = \frac { k Q _ { 1 } Q _ { 2 } } { d ^ { 2 } }\)
• B) \(B = k Q _ { 1 } Q _ { 2 } d ^ { 2 }\)
• C) \(B = \frac { k Q _ { 2 } } { Q _ { 1 } d ^ { 2 } }\)
• D) \(B = \frac { k Q _ { 1 } } { Q _ { 2 } d ^ { 2 } }\)
• E)\(B = \frac { k d ^ { 2 } } { Q _ { 1 } Q _ { 2 } }\)
