An engine has an efficiency of 1/6. When the temperature of sink is reduced by 62∘C62^\circ C its efficiency is doubled. Temperatures of the source is 37∘C37^\circ C 62∘C62^\circ C 99∘C99^\circ C 124∘C124^\circ C.

Multiple Choice Options

  • A K 0 /2 and K 0
  • B K 0 and 2K 0
  • C K 0 and K 0
  • D 0 and 2k 0

Step-by-Step Verified Solution

Kinetic energy + potential energy = total energy When kinetic energy is maximum, potential energy is zero and vice versa. _ Maximum potential energy = total energy. 0 + K 0 = K 0 (K.E. + P.E. = total energy).
