A body of mass 10kg is placed on rough surface pulled by a force F making an angle of `30^@` above the horizontal . If the angle of friction is also `30^@`, then the minimum magnitude of force F required to move the body is equal to (take , g= `10ms^(-2)`)

A body of mass 10 kg is placed on rough surface, pulled by force F making an angle of 30^(@) above the horizontal. If the angle of friction is also 30^(@) , then the minimum magnitude of force F required to move the body is equal to ( take, g=10 ms^(-2) )

Pushing force making an angle theta to the horizontal is applied on a block of weight W placed on a horizontal table . If the angle of friction is phi , magnitude of force required to move the body is equal to :

Pushing force making an angle o to the horizontal is applied on the block of weight W placed on the horizontal table. If o is the angle of friction, the magnitude of the force required to move the body is equal to :

A body of mass 10 kg is lying on a rough plane inclined at an angle of 30^(@) to the horizontal and the coefficient of friction is 0.5. the minimum force required to pull the body up the plane is

A block of mass 10 kg is placed on the rough horizontal surface. A pulling force F is acting on the block which makes an angle theta above the horizontal. If coefficient of friction between block and surface is 4/3 then minimum value of force required to just move the block is (g = 10 m/s^2)

Pulling force making an angle theta to the horizontal is applied on a block of weight W placed on a horizontal table. If the angle of friction is alpha , then the magnitude of force is alpha , then the magnitude of force required to move the body is equal to
