⚠️⚠️ A map shows that a star is 25 light years away. If you get in a ship and travel to this star at 0.95c, How far will the ship need to travel to reach this star?
C=the speed of light

Given :

A map shows that a star is 25 light years away.

To Find :

If you get in a ship and travel to this star at 0.95c, How far will the ship need to travel to reach this star.

Solution :

We know, 1 light year in km is given by :

So, 25 light years is given by :

Hence, this is the required solution.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
