How does the force of the car change as the mass of the car is increased?

yes

Explanation:

because if a car is 100 pounds then it will have less force than a 250 pound car

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
