match the statements from Table -1 with the the values in Table -2 and select the correct answer using the code given below.

A block of mass 10 kg is placed on a horizontal surface as shown in the figure and a force F = 100 N is applied on the block as shown, in the figure. The block is at rest with respect to ground. If the contact force between block and ground is 25n (in Newton) then value of n is : (Take g = 10 m//s^(2))

A plank of mass 10kg rests on a smooth horizontal surface. Two blocks A and B of masses m_(A)=2kg and m_(B)=1kg lies at a distance of 3m on the plank as shown in the distance of 3m on the plank as shown in the figure. The friction coefficient between the blocks and plank are mu_(A)=0.3 and mu_(B)=0.1 . Now a force F = 15 N is applied to the plank in horizontal direction. Find the time after which block A collides with B.

A block of mass m=5kg is resting on a rough horizontal surface for which the coefficient of friction is 0.2 . When a force F=40N is applied, the acceleration of the block will be (g=10m//s^(2)) .

A block of mass 5 kg is placed on a plank of mass 10 kg which is placed on the smooth horizontal surface as shown in figure. If a 100 N force is applied on the plank then the acceleration of the plank wrt ground is (Coefficient of friction between block and plank mu_s= mu_k=0.4 and g = 10 m/s^2 )

A constant force F=m_2g/s is applied on the block of mass m_1 as shown in figure. The string and the pulley are light and the surface of the table is smooth. Find the acceleration of m_1

A constant force F=m_2g/s is applied on the block of mass m_1 as shown in figure. The string and the pulley are light and the surface of the table is smooth. Find the acceleration of m_1

A plank of mass m is placed on a smooth surface. Now, a uniform solid sphere of equal mass m and radius R is placed on the plank as shown in the figure. A force F is applied at topmost point of the sphere at an angle of 45^(@) to the horizontal. Surface between the plank and the sphere is extremely rough so that there is no slip between the plank and the sphere. The force of firction acting between the plank and the sphere is (F)/(ksqrt(2)) . Find the value of k .
