SSC CGL 18th April 2022 Shift-1

Surface tension

Velocity

Linear momentum

Plane angle

- Option 1: Surface tension

- Surface tension is the force acting per unit length on the surface of a liquid.

- It is not related to the arc/radius expression.

- Option 2: Velocity

- Velocity is the rate of change of displacement with time.

- It involves distance and time, not arc/radius.

- Option 3: Linear momentum

- Linear momentum is the product of mass and velocity of an object.

- It does not involve arc or radius.

- Option 4: Plane angle

- Plane angle is measured as the arc length divided by radius.

- It is expressed in radians and corresponds to the arc/radius expression.

- This is the correct answer.
