  Figure shows three arrangements of electric field lines. In each arrangement, a proton is released from rest at point $ A $ and then accelerated through point $ B $ by the electric field. Points $ A $ and $ B $ have equal separations in the three arrangements. If $ p_{1}, p_{2} $ and $ p_{3} $ are linear momentum of the proton at point $ B $ in the three arrangement respectively, then

  

  • $ p_{1} > \, p_{3} > \, p_{2} $
  • $ p_{1} > \, p_{2} > \, p_{3} $
  • $ p_{2} > \, p_{1} > \, p_{3} $
  • $ p_{3} > \, p_{2} > \, p_{1} $

  The only force acting on a $ 2 \,kg $ body that is moving in $ xy- $ plane has a magnitude of $ 5\, N $ . The body initially has a velocity of $ 4 \,m/s $ in the positive $ x $ -direction. Some time later, the body has a velocity of $ 6 \,m/s $ in the positive $ y- $ direction. The work done on the body by the $ 5 \,N $ force during this time is

  • 20 J
  • 40 J
  • 50 J
  • 72 J
