  • Two objects resting on a table. Mass of object 1 (m1) = 1 kg, mass of object 2 (m2) = 2 kg, Acceleration due to g

Two objects resting on a table. Mass of object 1 (m1) = 1 kg, mass of object 2 (m2) = 2 kg, Acceleration due to gravity (g) =9.8 m/s2. Determine the magnitude and direction of the normal force (R1) exerted by m2 on the m1 and the normal force (R2) exerted by the table on the m2.

Option: 1

R1=9.8 N, R2=15.4 N
 


Option: 2

R1=12 N, R2=17N


Option: 3

R1=9.8 N, R2=29.4 N

 


Option: 4

R1=10 N, R2=26 N

FBD for m1

As there is no motion in a vertical direction, therefore the forces in the vertical direction will be equal.

So, R_1=W_1=m_1 \times g= 9.8 N

 

FBD for  m2

Here \ R_2= W_2+W_1=(m_2 \times g)+ W_1=(2\times 9.8)+ 9.8= 29.4 N
