THE RESULTANT OF TWO FORCES IS 50N. IF THE FORCES ARE PERPENDICULAR TO EACH OTHER AND ONE OF THEM MAKES AN ANGLE OF 30° WITH THE RESULTANT, FIND ITS MAGNITUDE
A. 100.0N B. 57.7N C. 43.3N ✓ D. 25.0N The answer to the question is: C. 43.3N To solve this problem, we can use vector addition and trigonometric functions. Let’s denote the magnitude of the first force as F1 and the magnitude…
A RAY OF LIGHT STRIKES A PLANE MIRROR AT AN ANGLE OF INCIDENCE OF 35°. IF THE MIRROR IS ROTATED THROUGH 10°, THROUGH WHAT ANGLE IS THE REFLECTED RAY ROTATED
A. 70° B. 45° C. 25° D. 20° ✓ The answer to the question is: D. 20° When a ray of light strikes a plane mirror, the angle of incidence is equal to the angle of reflection. According to the law of…
