To solve this problem we will use the vector concept given by the cross product between two perpendicular vectors and which results in a vector perpendicular to these two. From the definition of the Magnetic Force we have to
From the property of cross product the magnetic force should point in the direction perpendicular to the plane containing the vectors v and B.
The direction of velocity is north, and the direction of the magnetic force is northeast.
This cannot be the case, as the direction of magnetic force is not perpendicular to the direction of velocity of the charge.
Therefore the correct option for the direction of the magnetic field is <em>"This situation cannot exist because of the relative orientations of the velocity and force vectors" </em>

This state of motionlessness occurs because all of the kinetic energy in the car is absorbed by the spring in the form of elastic potential energy. The mathematical representation is:
1/2 mv² = 1/2 kx²
25m = kx², where m is the mass of the cart, k is the spring constant and x is the spring's extension.
Answer:
The box 1 moves faster.
Explanation:
lets
Mass =m kg
Initial velocity = u m/s
Initial velocity of box = 0 m/s
Let stake mass of block = m
When ball bounces back:
The final speed of the box = v
Final speed of ball = - u
Pi = Pf ( From linear momentum conservation)
m x u + m x 0 = m ( - u) + m v
mu + mu = m v
v= 2 u
When ball get stuck :
The final speed of ball and box = v
Pi = Pf ( From linear momentum conservation)
m x u + m x 0 = (m+m) v
v= u /2
So the box 1 moves faster.
The correct option is B.
As we are told in the question, the cabbage and broccoli grow best in clay soil. From the options we are given, it can be seen that it is only option B that has the highest amount of clay soil. The soil that will be used should be one that has the highest content of clay.
