Q7.17Multiple choice
A uniform cube of mass m and side a is placed on a frictionless horizontal surface. A vertical force F is applied to the edge as shown in Fig. 7.8. Match the following (most appropriate choice): (a) mg/4 < F < mg / 2
This question refers to a figure in the original PDF.
- (i)Cube will move up. (b) F > mg/2
- (ii)Cube will not exhibit motion. (c) F > mg
- (iii)Cube will begin to rotate and slip at A. (d) F = mg/4
- (iv)Normal reaction effectively at Fig. 7.8 a/3 from A, no motion.
