A pendulum is hanging from the ceiling of a cage. When the cage is moving up with certain acceleration and when it is moving down with the same acceleration, the tensions in the string are `T_(1)` and `T_2` respectively. When the cage moves horizontally with the same acceleration, the tension in the string is,

Options

A. `sqrt(2(T_1^2 + T_1^2))`
B. `sqrt((T_1^2 + T_2^2)/(2))`
C. `sqrt(2(T_1^2 - T_1^2))`
D. `sqrt(T_1^2 + T_1^2)`

Answer

B
