MCQ
Three forces start acting simultaneously on a particle moving with velocity $\vec{v}_{.}$ These forces are represented in magnitude and direction by the three sides of a triangle ABC (as shown). The particle will now move with velocity 

Image
  • A
    less than $\vec{v}_{.}$
  • B
    $|\vec{v}|$, in the direction of the largest force BC
  • C
    greater than $\vec{v}$
  • ✓
    $\vec{v}$ , remaining unchanged
✓

Answer

Correct option: D.
$\vec{v}$ , remaining unchanged
(D)$\vec{v}$, remaining unchanged
Explanation:
Net force on the particle is zero so the $\vec{v}$ remains unchanged.

Suppose you have taken a dilute solution of oleic acid in such a way that its concentration becomes $0.01 \,cm ^{3}$ of oleic acid per $cm ^{3}$ of the solution. Then you make a thin film of this solution (monomolecular thickness) of area $4\, cm ^{2}$ by considering $100$ spherical drops of radius $\left(\frac{3}{40 \pi}\right)^{\frac{1}{3}} \times 10^{-3}\, cm .$ Then the thickness of oleic acid layer will be $x \times 10^{-14} \,m$. Where $x$ is ...... .

The coil in a moving coil galvanometer experiences torque proportional to current passes through it. If a steady current $i$ is passed through it the steady deflection of the coil is found to be $90^o$ . Now the steady current is switched off and a charge $q$ is suddenly passed through coil. If the coil has $N$ turns of area $A$ and its moment of inertia is $I$ about the axis it is going to rotate then the maximum angle through which it deflects upon passing charge $q$ is
