Consider the quantities, pressure, power, energy, impulse, gravitational potential, electrical charge, temperature, area. Out of these, the only vector quantities are

(a) Impulse, pressure and area

(b) Impulse and area

(c) Area and gravitational potential

(d) Impulse and pressure

<p>This is a Multiple Choice Questions as classified in NCERT Exemplar</p><p><strong>Answer- b</strong></p><p><strong>Explanation</strong> – we know that impulse J= f.<span contenteditable="false"> <math> <mo>? </mo> <mi>t</mi> </math> </span>= <span contenteditable="false"> <math> <mo>? </mo> <mi>p</mi> </math> </span>, where F is force .<span contenteditable="false"> <math> <mo>? </mo> <mi>t</mi> </math> </span> &nbsp;is time duration and<span contenteditable="false"> <math> <mo>? </mo> <mi>p</mi> </math> </span> &nbsp;is change in momentum. As <span contenteditable="false"> <math> <mo>? </mo> <mi>p</mi> </math> </span>is a vector quantity, hence impulse is also a vector quantity. Sometimes area can also be treated as vector.</p>
