Answer:
a) No
b) No
Explanation:
When a bat is hit in a game of baseball such that it flies out of the field that means it is going with some angle to the horizontal.
a)
Then is such a case the velocity of the ball is never parallel to the acceleration because there acts a net acceleration which is resultant of the acceleration due to the applied force and the acceleration due to gravity but a component of the velocity when the ball descends the height acts parallel to the gravity.
b)
At no point during the motion of the ball its velocity is perpendicular to its acceleration because it has an initial angle of projection form the horizontal.
The moral law is to follow the 10 commandments, set forth and multiply, spread the word of god, and to obey the word of god. I really hope this works and if not I’m sorry. :’)
Answer:
Explanation:
electric field = 2170 N/C
now the speed of the charge particle is given as
here we know that charge particle moves without any deviation
so we will have
now magnetic field in this region is given as
Now another charge particle enters the region with different speed and experience the force upwards
