Two blocks of masses 2 kg and 4kg are connected through a massless inextensible string. The co-efficient of fricition between 2kg block and ground is 0.4 and the coefficient of friction between 4kg block and ground is 0.6. The forces F_(1)=10N and F_(2)=20N are applied on the blocks as shown in the figure. Calculate the frictional force between 4 kg block and ground (Assume initially the tension in the string was just before forces F_(1) and F_(2) wer applied).

Two bodies A and B of masses 10 kg and 5 kg placed very slightly seperated as shown in figure The coefficient of friction between the floor and the block are as mu_(s) = 0.4 block A is pushed by an external force F The value of F can be changed when the weight between block A and ground breaks block A will start prssing block B will start pressing the vertical wall If F = 50N the friction force acting between block B and ground will be

Two blocks of 2 kg and 4 kg are connected by a light string and kept on horizontal surface A force of 16 N is acted on 4 kg block horizontally as shown in figure. Besides ,it is given that coefficient of friction between 4 kg and ground is 0.3 and between 2 kg block and ground is 0.6 . Then frictional force between 2 kg block ground is
