Question

Can anyone tell me the ans of que no.

Fast plz

Answer 1

2K/V^2

2(1/2×m×V^2)/V^2

2m/2

= m

So answer is mass

Answer 2

$\mathfrak{\huge{\underline{Question\: :-}}}$

Physical quantity obtained by $\frac{2K}{V^2}$

Where

K = Kinetic energy

V = Linear velocity

$\mathfrak{\huge{\underline{Answer\: :- }}}$

As we know that

Kinetic energy = $\frac{1}{2}mV^2$

Then by putting value of Kinetic energy in equation

we get

$\frac{2 \times \frac{1}{2}mV^2 }{V^2}$

Then equation after cancellation of V² and 2 the remaining part = mass(m)

Hence the physical quantity obtained

= $\boxed{\texttt{mass}}$

Hope it helps
