Answer:
98N and 147N
Explanation:
We have the following information:

We can find the static fricton force as follow,

Where N is the normal force (mg)

Static friction force at 147N is greater than the force applied hence body does not move.

Answer: 
The following vectors have been given: 
The angle between these two vectors can be found by:
