Answer:Work = 0.68 mc²Explanation:given dataspeed = 0.084 cc

solutionas kinetic energy of mass particle is

KE = mc²( – 1 ) …………1

here is lorentz constant

=

=

= 1.68as here particle start from rent so initial KE is 0

and final KE = mc²(1.68 – 1 )

final KE = 0.68mc²

so here work done to increase speed of particle

W = final KE – initial KE

Work = 0.68 mc²
