  1. Understand the question

    If you have two charges, where charge 1 is a large + charge, and charge 2 is a small negative charge, which two are correct about the forces each charge feels 11 points They exert an attractive force on eachother Charge 1 exerts a larger force on charge 2 Charge 2 exerts a larger force on charge 1 They exert a repulsive force on eachother Only the negative charge exerts a force Only the positive charge exerts a force They exert equal forces on each other due to n3rd law This is a required question If you double the left charge only, what happens to the force 11 points gets cut in half doubles quadrupples gets cut into 1/4 If you double the right charge only, what happens to the force 11 points gets cut in half doubles quadrupples gets cut into 1/4 If you cut the left charge in half, what happens to the force 11 points gets cut in half doubles quadrupples gets cut into 1/4 If you cut both charges in half, what happens to the force 11 points gets cut in half doubles quadrupples gets cut into 1/4 If you double both charges, what happens to the force 11 points gets cut in half doubles quadrupples gets cut into 1/4 If you cut the separation distance in half what happened 11 points the force doubled the force quadruppled the force cut in half the force cut into 1/4 If you doubled the separation distance what happened 11 points the force doubled the force quadruppled the force cut in half the force cut into 1/4 Look up the equation for Coulombs law record in your notes; in your journal write down what each symbol means, even the numerical value for the constant. This formula should show the relationship between electrical forces and the factors that influence it. (charge strength of both charges interacting, and separation distance). Which relationships are true? (2 answers) * 12 points Direct relationship between distance and force inverse relationship between distance and force inverse square relationship between distance and force direct relationship between each charges strength and force direct square relation

  2. Brief Explanations
    1. Opposite charges attract; Newton's 3rd law means forces are equal.
    2. Coulomb's law: \( F \propto q_1 \), so doubling \( q_1 \) doubles force.
    3. \( F \propto q_2 \), so doubling \( q_2 \) doubles force.
    4. \( F \propto q_1 \), so halving \( q_1 \) halves force.
    5. \( F \propto q_1q_2 \), so halving both gives \( \frac{1}{2} \times \frac{1}{2} = \frac{1}{4} \) force.
    6. \( F \propto q_1q_2 \), so doubling both gives \( 2 \times 2 = 4 \) force.
    7. \( F \propto \frac{1}{r^2} \), so halving \( r \) gives \( \frac{1}{(1/2)^2} = 4 \) force.
    8. \( F \propto \frac{1}{r^2} \), so doubling \( r \) gives \( \frac{1}{2^2} = \frac{1}{4} \) force.
    9. Coulomb's law: \( F = k\frac{q_1q_2}{r^2} \); force is proportional to charge product and inverse square of distance.
  3. Final answer
    1. They exert an attractive force on each other, They exert equal forces on each other due to n3rd law
    2. doubles
    3. doubles
    4. gets cut in half
    5. gets cut into 1/4
    6. quadrupples
    7. the force quadruppled
    8. the force cut into 1/4
    9. inverse square relationship between distance and force, direct relationship between each charges strength and force
