Answer #1

3, 53丁 ro 2.

there is no friction between 50 kg and 10kg block's contact surface because there is no relative motion between them (since they both will stay on the wedge)

T is tension in the string

N​​​​​​1 is normal reaction b/w 5 and 50kg blocks, similarly for all other cases

and f​​​​​​1 is friction b/w 5 and 50 kg blocks and similarly for othe cases and g is acceleration due to gravity
