<u>Correct Option:</u>
X shows positive while Y shows negative charges, create the electric field as shown.
<u>Option: D</u>
<u>Explanation:</u>
The idea of an electric field provides a way to define how starlight travels to enter our eyes across huge distances of empty space.The electric field is a quantity of vectors that is present at any point in space. The electric field at a region shows the force that, if put at that position, will operate upon a positive charge device.
The direction of the electric field points directly at a positive point charge, and straight at a negative point charge. The field direction is implemented to the force direction exert on a positive test charge. It is externally from a positive charge and radially in toward a negative point charge.
Answer:
(a) 2.5 cm
(b) Yes
Solution:
As per the question:
Mass of Uranium-235 ion, m =
Mass of Uranium- 238, m' =
Velocity, v =
Magnetic field, B = 0.250 T
q = 3e
Now,
To calculate the path separation while traversing a semi-circle:
The radius of the ion in a magnetic field is given by:
R =
Now,
By putting suitable values in the above eqn:
(b) Since the order of the distance is in cm, thus clearly this distance is sufficiently large enough in practical for the separation of the two uranium isotopes.
