Answer:

4 Discuss passing pointer to a function with example

Answer

Answer 2

Explanation:

Two balls of charges q1 and q2, initially have exactly same velocity. Both the balls are subjected to same uniform electric field for same time. As a result , the velocity of the first ball is reduced to half of its initial value and its direction changes by 60° .The direction of the velocity of second ball is found to change by 90.

The electric field and initial velocity of the charged particle are inclined at angle

1)60. (2)30

3) 90. (4)150
