` f_(l1)= mu_(1) m_(1) g = 0.1 xx 2 xx 10 = 2 N`
`f_(l2)= mu_(2) m_(2) g = 0.2 xx 3 xx 10 = 6 N`
` T + f_(l2) = 8 rArr T = 2 N`
`f_(1) + 1 = T rArr f_(1) = T - 1 = 2 - 1 = 1 N`

Find tension in the string between blocks 3kg and 4kg. Friction is negligible.

On increasing the tension in the string by 10 kg wt, the fundamental frequency increases in the ratio of 1 : 2. Calculate the initial tension in the string.

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).
