Iteru [2.4K]4 years ago
5 0

Given:-

  • Distance covered by the particle (s) = 20 m
  • Time taken (t) = 4 seconds

To Find: Speed of it.

We know,

v = s/t

where,

  • v = Speed,
  • s = Distance &
  • t = Time taken.

Putting the values,

v = (20 m)/(4 s)

→ v = 5 m/s (Ans.)

A particle that has an 7.3-μC charge moves with a velocity of magnitude 4 × 105 m/s along the +x axis. It experiences no magneti
vovangra [49]

If the particle's velocity were perpendicular to the magnetic field, the magnetic force would be given by:

F = qvB

F is the magnetic force, q is the charge, v is the velocity, and B is the magnetic field strength.

Given values:

F = 0.320N

q = 7.3×10⁻⁶C

v = 4×10⁵m/s

Plug in the values and solve for B:

0.320 = (7.3×10⁻⁶)(4×10⁵)B

B = 0.110T

The magnetic force depends on the cross product between the particle's velocity vector v and the magnetic field vector B. If v and B are parallel then the cross product is 0. v points in the +x direction, therefore B must point in either the +x or -x direction.

The displacement (in meters) of a particle moving in a straight line is given by the equation of motion s = 6/t2, where t is mea
ycow [4]

Answer:

Velocity of the particle at time t = a

        v(a)=-\frac{12}{a^3}

Velocity of the particle at time t = 1

         v(1)=-12m/s

Velocity of the particle at time t = 2

         v(2)=-1.5m/s

Velocity of the particle at time t = 3

          v(3)=-0.44m/s

Explanation:

Displacement,

          s(t)=\frac{6}{t^2}

Velocity is given by

          v(t)=\frac{ds}{dt}=\frac{d}{dt}\left ( \frac{6}{t^2}\right )=-\frac{12}{t^3}

Velocity of the particle at time t = a

        v(a)=-\frac{12}{a^3}

Velocity of the particle at time t = 1

         v(1)=-\frac{12}{1^3}=-12m/s

Velocity of the particle at time t = 2

         v(2)=-\frac{12}{2^3}=-1.5m/s

Velocity of the particle at time t = 3

          v(3)=-\frac{12}{3^3}=-0.44m/s
