The answer is A) 1000 J
According to the law of conservation of energy, the total energy before an action is always equal to the total energy after the action.
So that is, the total energy is 8000J found as potential energy, 7000J has transformed into kinetic energy, then the thermal energy should be the remaining 1000J.
Hope this helps.

The linear velocity of the point is tangent to the circle; the
point’s linear speed v is given by
v vr (radian measure), (10-18)
wherev is the angular speed (in radians per second) of the body.
The linear acceleration of the point has both tangential and
radial components.The tangential component is
at ar (radian measure), (10-22)
where a is the magnitude of the angular acceleration (in radians
per second-squared) of the body.The radial component of is
(radian measure). (10-23)
If the point moves in uniform circular motion, the period T of
the motion for the point and the body is
(radian measure).</span>
