a) The acceleration of the block for the first configuration is
.
b) The acceleration of the block for the second configuration is
.
Further Explanation:
Given:
The magnitude of force
is
.
The magnitude of force
is
.
The mass of the object is
.
Concept:
<u>Part (a):</u>
The situation in which the
acts in positive X direction and
in the positive Y direction is as shown in figure attached below.
Since the two forces are perpendicular to each other, the net force acting on the object will be:

The angle at which the net force acts on the object is:

The acceleration of the object under the action of the net force is given by:

Substitute the values in above expression.

Thus, the acceleration of the object in the first configuration is
at an angle of
from horizontal.
<u>Part (b):</u>
In the second configuration as shown in the figure attached below, the force
is resolved into its horizontal and vertical components as follows:


The net force in the horizontal direction and the vertical direction are:

Thus, the resultant force acting on the object will be:

The angle at which the net force acts on the object is:

The acceleration of the object under the action of the net force is given by:

Substitute the values in above expression.

Thus, the acceleration of the object in the first configuration is
at an angle of
from horizontal.
