Q1 Two particles, A and B, of mass 3 kg and 2 kg respectively, are joined by a light inextensible string which passes over a fixed, smooth pulley. Initially, both particles are held at rest with
particle A 60 cm higher than particle B. Both particles are then released from rest,
a) Draw a diagram showing the forces acting on the masses,
b) How long is it after the particles are released before they are level?

Two lasers are shining on a double slit, with slit separation d. laser 1 has a wavelength of d/20, whereas laser 2 has a wavelength of d/15. the lasers produce separate interference patterns on a screen a distance 5.30 m away from the slits. part a which laser has its first maximum closer to the central maximum? view available hint(s) which laser has its first maximum closer to the central maximum? laser 1 laser 2
