Here I am giving you question paper for the 11th class of Kishore Vaigyanik Protsahan Yojana

Observe that, at any instant, the minute and hour hands of a clock make two angles between them whose
sum is 360º. At 6 : 15 the difference between these two angles is :
(A) 165º (B) 170º (C) 175º (D) 180º
Sol. (A)

Angle between them at 6:15 will be = 97.5
Other angle = 360 – 97.5 = 262.5
So difference = 262.5 – 97.5 = 165.0 = 165°

12. Two workers A and B are engaged to do a piece of work. Working alone, A takes 8 hours more to
complete the work than if both worked together. On the other hand, working alone, B would need 4 and half hours more to complete the work than if both worked together. How much time would they take to
complete the job working together ?
(A) 4 hours (B) 5 hours (C) 6 hours (D) 7 hours

Sol. (C)

Which of the following statements is true about the flow of electrons in an electric circuit ?
(A) Electrons always flow from lower to higher potential
(B) Electrons always flow from higher to lower potential
(C) Electrons flow from lower to higher potential except through power sources
(D) Electrons flow from higher to lower potential, except through power sources
Sol. (A)
Electrons always moves in direction opposite to that of direction of electric field. And potential drops in the
direction of electric field. Hence, electron moves from lower to higher potential.

19. A boat crossing a river moves with a velocity v relative to still water. The river is flowing with a velocity v/2
with respect to the bank. The angle with respect to the flow direction with which the boat should move to
minimize the drift is :
(A) 30º (B) 60º (C) 150º (D) 120º
