Answer:
Explanation:
The detailed steps are as shown below
- but magnitude of force F = √ [ 1 - v²/c²]
but acceleration twice as great as the force required to produce the same acceleration;
4 = 1 / [ 1 - v²/c²]
1/4 = 1 - v²/c²
v²/c² = 3/4
v/c = √ [3/4]
v = 0.87c
but speed of light c = 3 x 10^8m/s
v = speed of the particle = 0.87( 3 x 10^8m/s)
v = 2.61m/s
Some energy is always lost as heat
hope that helps! :))
