West Determine the magnitude of the force due to Earth's magnetic field if you throw the ball with a velocity of 6.0 m/s toward geographic west (Hint: 1T=1 kg/C-s) A 9.0 x 10-12 N B. 10x 104 N O C 25x 1013 N D. 11 x 1011 N
Three charges on the x-axis as shown below, if the distancesare in centimeters, find the net force on the fourth charge on they-axis.
Two protons in a molecule are 4.10 x 10-10 m apart. Find the electric force exerted by one proton on the other. Find the magnitude and direction, state how the magnitude of this force compares with the magnitude of the gravitational force exerted by one proton on the other, what must be a particle's charge-to-mass ratio if the magnitude of the gravitational force between two of these particles is equal to the magnitude of electric force between them?
Coulomb’s law tells us that the electrostatic force between two charged objects can be calculated by: ?= ??1?2/?^2Where k is a constant with a value of 8.99x109 Nm2/C2; ?1 and ?2 are the charges of the two particles (1.602x10-19 C), and r is the distance between the two particles. The force is attractive if the charges of the two particles is opposite (one’s positive and one’s negative) and repulsive if the charges have the same charge (both positive or both negative). Calculate the electrostatic force on proton #1 from the other two protons.Will the gravitational force between the protons be attractive or repulsive? What about the electrostatic force? Which has the larger magnitude, the electrostatic force or the gravitational force? Can the electrostatic and gravitational forces alone create a stable Lithium nucleus?
