Question

if a particle could move with the velocity of light . how much kinetic energy would it possesses ​

Answer 1

Answer:

mass×1.5×10¹⁶J

justice for ssr

Explanation:

ke=1/2×m×v²

=1/2 ×m×(3×10⁸)²

=1/2 ×3×10¹⁶×m

let m=1kg

ke=1.5×10¹⁶

Answer 2

Explanation:

Correct option is

D

9

K.E =

2

1

mv

2

Hence kinetic energy is directly proportional to the square of the velocity. Thus if we increase the kinetic energy by 3 times its velocity will be increased by 9 times.
