Three masses of 16kg, 8kg, and 4kg are placed in contact as shown in figure. If a force of 140N is applied on 16kg mass the force acting on 8kg mass is.

Two blocks of masses 2kg and 1kg are in contact with each other on a friction less table. When a horizontal force of 3N is applied on the block of mass 2kg, the value of the force of contact between the two blocks is.

Two masses m₁ and m₂ are placed on a smooth surface horizontally and connected by a light string as shown in figure A force F is applied on mass m₁, then the tension in the string T₂ is.

Two masses m₁ and m₂ are suspended from a rigid support through a light string. The tension in the string between support and mass m₁ is.

If the angle of friction is 45 $degree$ , then the coefficient of static friction is.

A block of mass 2kg lies on a horizontal surface and it is subjected to a vertical downward force 30N as shown in figure. The contact force between the block and surface is.

The free body diagram of block 'm' is

If $vertical line z vertical line equals 1$ and $z not equal to 1$ , then all the values of $fraction numerator z over denominator 1 minus z to the power of 2 end exponent end fraction$ lie on

Therefore the correct option is choice 4

If $vertical line z vertical line equals 1$ and $z not equal to 1$ , then all the values of $fraction numerator z over denominator 1 minus z to the power of 2 end exponent end fraction$ lie on

Therefore the correct option is choice 4

If $z$ is a complex number such that $vertical line equals vertical line greater or equal than 2$ then the minimum value of $∣ z plus fraction numerator 1 over denominator 2 end fraction$ is is strictly

Therefore the correct option is choice 4
