PolarNik [594]

Answer:

$x=3$

Explanation:

From the question we are told that:

Charge $Q=40 \mu C$

Length $L=20cm=0.20m$

Spring constant $k=120Nm^{-1}$

Generally the equation for Force between Charges is mathematically given by

$F=k\frac{q_1 q_2}{r^2}$

$F=9*10^9\frac{40*10^{-6}^2}{0.2^2^2}$

$F=360N$

Therefore

$F=kx$

$x=\frac{F}{k}$

$x=\frac{360}{120}$

$x=3$

Ipatiy [6.2K]

Answer:

The mass of the beam is = 29 kg.

Explanation:

A beam with mass 40 kg is shown in figure. Point S is the support point. Point B is the middle point on the beam where mass of the beam acts.

Taking moment about Point S

40 × 21 = $M_{beam}$ × 29

$M_{beam}$ = 29 kg

Therefore the mass of the beam is = 29 kg.
