The magnetic force on a charged particle is given as: F = qvBsinФ
B is the magnetic field.
q is the charge on the particle.
v is the velocity of the charged particle.
Ф is the angle between magnetic field (B) & the velocity of charge (v).
⇒ F = qvb sin Ф
Here, Ф = 90 degree.
and sin 90 = 1
Putting the values in the equation, we get,
F = 1.6 x 10^-19 C × 4.5 × 10^7 m/s × 1.6 T
= 11.52 × 10^-12N
= 1.2 x 10^-11 N up
Answer:
The ratio of lengths of the two mathematical pendulums is 9:4.
Explanation:
It is given that,
The ratio of periods of two pendulums is 1.5
Let the lengths be L₁ and L₂.
The time period of a simple pendulum is given by :
or
Where
l is length of the pendulum
or
....(1)
ATQ,
Put in equation (1)
So, the ratio of lengths of the two mathematical pendulums is 9:4.
Green because it is the color it does not absorb.

Answer:
133 kg
Explanation:
Parameters given:
Mass of tackler, m = 133 kg
Initial velocity of tackler, u = 3.4 m/s
Final velocity of tackler and receiver, v = 1.7 m/s
Since momentum is conserved, we apply the principle of conservation of momentum:
Total initial momentum = Total final momentum
mu + MU = (m + M)v
Where U = initial velocity of receiver = 0 m/s
M = mass of receiver
Therefore:
(133 * 3.4) + (M * 0) = (133 + M) * 1.7
452.2 = (133 + M) * 1.7
(133 + M) = 452.2/1.7
133 + M = 266
=> M = 266 - 133
M = 133 kg
The mass of the receiver is 133 kg.
