A wire of 9.8 xx 10^(-3) kg per meter mass passes over a fricationless pulley fixed on the top of an inclined frictionless plane which makes an angle of 30^(@) with the horizontal. Masses M_(1) & M_(2) are tied at the two ends of the wire. The mass M_(1) rests on the plane and the mass M_(2) hangs freely vertically downwards. the whole system is in equilibrium. Now a transverse wave propagates along the wire with a velocity of 100m/sec. Find the ratio of masses M 1 ​ to M 2 ​ .

A person pushes a block of mass 4 kg up a frictionless inclined plane 10 m long and that makes an angle of 30^@ with the horizontal . Then the work done is

The tops of two poles of height 40 m and 25 m are connected by a wire. If the wire makes an angle 30^(@) with the horizontal, then the length of the wire is

Two blocks each of mass M are resting on a frictionless inclined plane as shown in fig then:

An ideal massless spring S can compressed 1.0 m in equilibrium by a force of 1000 N . This same spring is placed at the bottom of a friction less inclined plane which makes an angle theta =30^@ with the horizontal. A 10 kg mass m is released from the rest at top of the inclined plane and is brought to rest momentarily after compressing the spring by 2.0 m. the distance through which the mass moved before coming to rest is.
