What is a co-initial vector?
A. Two or more vectors having the same magnitude are called co-initial vectors.
B. Two or more vectors are said to be co-initial if they are parallel to the same line irrespective of their magnitudes and directions.
C. Two or more vectors having the same initial point are called co-initial vectors.
D. None of the above.

Hint: A vector is a physical quantity with both magnitude and direction. In other terms, a vector is an object that contains both magnitude and direction. It depicts how an object moves from one location to another. The vector is depicted below with its head, tail, magnitude, and direction.

Complete answer:
Co-initial vector:If both of the supplied vectors have the same initial point, they are called co-initial vectors. OA and OB, for example, are two co-initial vectors.


Hence, the correct option is C.

Additional information:Vectors are used in chemistry to consider bond polarity; chemical bonds have one side that is slightly negatively charged and the other side that is slightly positively charged. This produces an electric field that runs from positive to negative, which must be taken into account in chemistry calculations. Vectors are useful in a variety of domains for solving systems with a large number of simultaneous equations.

Note:Position and momentum are perhaps the most essential vectors in elementary physics. These are used to compute the velocity of an item. Velocity (which tells you how fast an object is travelling), current density (which shows you how the entire current is distributed across the conductor), flux, and vector area are some additional useful vectors in undergrad physics.
