Primary cells are the ones which cannot be recharged and have to be discarded after the expiration of the lifetime whereas, secondary cells need to be recharged when the charge gets over. Both the types of battery are used extensively in various appliances and these cells differ in size and material used in them.

To solve the problem it is necessary to apply the concepts related to the conservation of linear Moment, that is to say
Where,
m = Mass
v = Velocity
P = Linear momentum
For the given data we have to:
The components of this force would be given by,
According to the definition given at the end of the problem, this component corresponds to that expressed for x and y.
Applying the previous equation we have,
<em>Note: The component at this direction must also decomposed</em>
The mass is 143g=0.143kg, then:
Therefore the final vector is:
Answer: It is both B and D
