Question 22 (1 point) Two objects, with masses m, and m2, are originally a distance R apart. The gravitational force between them has magnitude F. The second object has its mass changed to 2m2, and the distance is changed to R/4. What is the magnitude of the new gravitational force? OF/16 16F OF/32 32F Question 23 (1 point) A 1.67 x 10^-27 kg proton moving at 4.0 x 10^4 m/s horizontally enters a region where a magnetic field of 0.13 T is present, directed vertically downward. What force acts on the proton? O zero 1.4 x 10^-16 N 5.2 x 10^-16 N 8.3 x 10^-16 N Question 24 (1 point) A force of 10 N acts on a charge of 5.0 UC when it is placed in a uniform electric field. What is the magnitude of this electric field? 50 x 10^6 N/C 2.0 x 1016 N/C 0.50 x 1016 N/C 1000 x 10^6 N/C
