3. A 200 g tennis ball moving with a velocity of 15 m s' along x axis collides with a stationary ball of 800 g as shown in figure below. After the collision, tennis ball is scattered at an angle, 45° from its original direction with velocity of 5 ms. Find the final velocity (magnitude de direction) of the struck ball (Ans: 3.00 ms-1; 17.14°) ​

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
