The correct answer to the question is vertically downward i.e towards the centre of earth.
EXPLANATION:
As per the question, the box is pulled to the right.
Hence, the direction of the applied force is towards right.
We are asked to determine the direction of the gravitational force that acts on the body.
Before answering this question, first we gave to understand the gravitational force of earth.
Any body present on the surface of earth is attracted with the force of gravity of earth ( gravitational force ) towards its centre.  It is equivalent to the weight of the body.  
 The force of gravity is always directed towards the centre of earth irrespective of the nature of applied force.
Hence, the direction of the gravitational force which acts on the box is vertically downward.
 
        
                    
             
        
        
        
"physical science" is a branch of science that is based on practical tests and explanations of the different phenomena. It is based on scientific evidence and tests/experiments.
Some of the branches that are based on physical science are:
1- Astronomy
2- Electronics
3- Engineering
4- Radiology
        
                    
             
        
        
        
Answer:
268.22m/s
Explanation:
Given; 
     10mile/min to m/s 
 We need to convert between the two units;
   Using the dimensions; 
     1 mile  = 1609.34m 
      60s  = 1min 
Now; 
     10 x  x
 x  x
 x 
   = 268.22m/s
