Auser needs to open some files that are being shared from a remote computer. however, the user receives an "access denied" message when trying to open some files and folders. what is a probable cause of this?

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
