Pick out the only vector quantity in the following list:
Temperature, pressure, impulse, time, power, total path length, energy, gravitational potential, coefficient of friction, charge.
Impulse : Impulse is given by the product of force and time. Since force is a vector quantity, its product with time (a scalar quantity) gives a vector quantity.
Classify the given physical quantities in vector and scalar. Position, speed, velocity, pressure, acceleration, temperature, force, work, energy.
Pick out the two scalar quantities in the following list :
force, angular momentum, work, current, linear momentum, electric field, average velocity, magnetic moment, relative velocity.
If $\vec P = \vec Q$ then which of the following is NOT correct
If $\overrightarrow A $ is $(3,\, 4)$ unit, then show that the value of its unit vector is $1$.
Find the unit vector of a vector whose co-ordinates are $(8,\, 6)$.
