PYQ NEET- Introduction To Vector Operations
2018:
The force acting on the body is 20 N. The mass of the body is 5 kg. The angle between the force and the horizontal is 60°.
The acceleration of the body can be found using the following formula:
a = F / m
Where:
ais the acceleration of the body in m/s^2Fis the force acting on the body in Nmis the mass of the body in kg
In this case, the acceleration of the body is:
a = 20 N / 5 kg = 4 m/s^2
Therefore, the acceleration of the body is 4 m/s^2.

The vector A is given by A = 2i + 3j - 4k. The vector B is given by B = i + j + k.
The vector A + B can be found by adding the components of the two vectors:
A + B = (2i +
