Refer to the attached figure. Xp may not be between the particles but the reasoning is the same nonetheless.
At xp the electric field is the sum of both electric fields, remember that at a coordinate x for a particle placed at x' we have the electric field of a point charge (all of this on the x-axis of course):
Now At xp we have:
Which is a second order equation, using the quadratic formula to solve for xp would give us:
or
Plug the relevant values to get both answers.
Now, let's comment on which of those answers is the right answer. It happens that
BOTH are correct. This is simply explained by considring the following.
Let's place a possitive test charge on the system This charge feels a repulsive force due to q1 but an attractive force due to q2, if we place the charge somewhere to the left of q2 the attractive force of q2 will cancel the repulsive force of q1, this translates to a zero electric field at this x coordinate. The same could happen if we place the test charge at some point to the right of q1, hence we can have two possible locations in which the electric field is zero. The second image shows two possible locations for xp.
Answer:(1)=current (2)=force (3)=magnetic field (4)=reverse
Explanation:When there's a current in The coil. A force act on each side Of The coil. This is because the coil is in a magnetic field, the direction Of The spin would reverse
Because charge is quantized, the answer is no.
Answer:
Angular acceleration is defined as the rate of change of angular velocity of a body.
consider the attached figure as shown
It rotates with an angular velocity
An point inside the object rotates along the path as indicated thus turning by an angle in time 't'
Thus we have
physically angular acceleration can be understood as the rate at which the angular speed of any object is changing with time.
