Dimensional formula of magnetic flux is

✓
$M{L^2}{T^{ - 2}}{A^{ - 1}}$
B
$M{L^0}{T^{ - 2}}{A^{ - 2}}$
C
${M^0}{L^{ - 2}}{T^{ - 2}}{A^{ - 3}}$
D
$M{L^2}{T^{ - 2}}{A^3}$

✓

Answer

Correct option: A.

$M{L^2}{T^{ - 2}}{A^{ - 1}}$

a
(a) $\phi = BA = \frac{F}{{I \times L}}A $

$= \frac{{[ML{T^{ - 2}}]\,\,[{L^2}]}}{{[A]\,\,[L]}} $

$= [M{L^2}{T^{ - 2}}{A^{ - 1}}]$

A massless spring $(k = 800\, N/m)$, attached with a mass $(500\, g)$ is completely immersed in $1\, kg$ of water. The spring is stretched by $2\, cm$ and released so that it starts vibrating. What would be the order of magnitude of the change in the temperature of water when the vibrations stop completely? (Assume that the water container and spring receive negligible heat and specific heat of mass $= 400\, J/kg\, K$, specific heat of water $= 4184\, J/kg\, K$)

A person is swimming with a speed of $10\, m /s$ s at an angle of $120^{\circ}$ with the flow and reaches to a point directly opposite on the other side of the river. The speed of the flow is $'x'$ $m / s$. The value of $'x'$ to the nearest integer is ..............

Two generators $S_1$ and $S_2$ produce water wave of equal frequency. A point $P$ is located such that $(S_1P -S_2P)$ is equal to half a wavelength. When operated alone, $S_1$ produces an oscillation of amplitude $2a$ at $P$ while $S_2$ produces an oscillation of amplitude $a$ . If the generators are operated in phase, which graph correctly shows the resultant oscillation at $P$ ?

Given below are two statements. One is labelled as Assertion $A$ and the other is labelled as Reason $R$.

Assertion A :Two identical balls $A$ and $B$ thrown with same velocity '$u$ ' at two different angles with horizontal attained the same range $R$. If $A$ and $B$ reached the maximum height $h_{1}$ and $h_{2}$ respectively, then $R =4 \sqrt{ h _{1} h _{2}}$

Reason R: Product of said heights.

$h _{1} h _{2}=\left(\frac{u^{2} \sin ^{2} \theta}{2 g }\right) \cdot\left(\frac{u^{2} \cos ^{2} \theta}{2 g }\right)$
