Part I : Questions (Choose the correct answer) 1. B A r r , and C r are three vectors directed along the x, y and z axes respectively as shown. If A = B = 4 and C = 2 then the value of ( ) C B A r r r × is * 4 * 8 * 16 * 32 2. A particle is moving along the x-axis with constant acceleration a = 1m/s 2 . The graph which represents this motion is 3. A particle is rotating clockwise in a horizontal circle . If the velocity and acceleration of this particle at point A are 3 j ˆ m/s and 3 i ˆ m/s 2 , respectively, then the figure in which point A satisfies this condition is 4. Two blocks are connected by a rope and lifted upward by a force F as shown in the figure. If the blocks move with constant velocity, then the tension T between the two blocks is given by * T = F * T = F-mg * T = F – 2mg * T = F-3mg m 2m F T x z y A r B r C r x y A x y A x y A x y A (a) (b) (c) (d) 0 0 0 0 Ver - A
