7. A particle with virtually no mass is resting on an inclined plane as shown. Two forces act on it. There is no friction. a) Find the total force pushing the particle directly against the plane. (ie: perpendicular to the plane) (Choose the correct answer and just circle the letter of the correct answer.) 140 N A. 225 N B. 112,5 N C. 213, 6N D. 150,8 N 85 N- E. 163,7 N F. 194,8 N 30° 90° b) What will the particle do under the action of these forces? (Choose the correct answer) A. move up the plane C. move down the plane B. remain at rest.
