Answer:
The magnitude of force is
Solution:
As per the question:
The strength of Electric field due west at a certain point,
Charge, Q = - 6 C
Now, the force acting on the charge Q in the electric field is given by:
Here, the negative sign indicates that the force acting is opposite in direction.
Answer:
Part A:
Part B:
Part C:
Explanation:
Part A:
We will use the following kinematics equation:
Part B:
We will use the same kinematics equation:
Part C:
The total time takes is 2t.
So the train moves a distance of
And the car moves a distance in Part A and in Part B:
So the total distance that the car traveled is
The difference between the train and the car is
Answer:
The correct solution is "122.2211".
Explanation:
Given:
deceleration,
a = 22 ft/sec²
Initial velocity,
Now,
Now,
Final velocity,
Initial velocity,
hence,
⇒
By putting the values, we get
