Question A: part 2 & 3. Thank you!

Clear my.choice Question 2 answered At a particular location near the earth's surface, weather conditions produce an electric field that has a magnitude of 171 N/C pointing directly down toward the ground. A charged piece of plastic is then released in this field. If the electric field causes an electric force on the plastic of 0.37e3 N directed towards away from the ground in the opposite direction as the electric field, what is the magnitude and sign of the charge on the piece of plastic Points out of 100 P Flag question Select one 462 x 10°C -2.16 x 10°C -6.33 X 102 -4.62 x 100c +2.16 x 10°C Question 3 Notyou answered The first satelite to orbit the Earth, Sputnik 1, launched by Soviets in October 1952 carried radio beacons on the frequency of 40 MHz.
