A) A clock when taken on a mountain can be made to give correct time, if we change the length of pendulum suitably
B) An increase in value of g makes a clock to slow
C) If the length of a pendulum is increased the clock becomes fast
D) A clock when taken to a top mine or carried to the top of mountain become slow
Correct Answer: D
Solution :
Above or below the earth surface, value of acceleration due to gravity decrease, so time period \[\left( \frac{1}{V(volume)} \right)\] increases, i.e., clock will become slow.
