A metal sphere with a mass of $5kg$ is

suspended by two strings and at rest as

shown here.

a$.(2)$Draw a FBD on the dot below.

b$.(2)$Without doing any calculations, explain why the tension in the $2m$ long string must be greater

than the tension in the horizontal string.

bc ol angle?

c$.(4)$The horizontal string is cut and the mass swings down to the lowest point shown in the

diagram. When the mass gets to the lowest point, calculate the tension in the string.
