Part A

the work done on it by gravity and the work done on it by the tension in the string are both equal to zero.

the work done on it by gravity is $\backslash (\backslash$mathbf$\{-118\}\backslash$mathrm$\{$J$\}\backslash )$ and the work done on it by the tension in the string is zero.

the work done on it by gravity is $-118$ J and the work done on it by the tension in the string is $+118$ J $.$

the work done on it by gravity is $+118$ J and the work done on it by the tension in the string is $-118$ J $.$

the work done on it by gravity and the work done on it by the tension in the string are both equal to $-118$ J$.$
