Calculate the speed of Jupiter if the mass of Jupiter is `1.9 xx 10^(27) kg`. Distance from the sun is `7.8 xx 10^(11)m` and the mass of the sun is `2 xx 10^(30) kg`.

Explanation

To calculate the speed of Jupiter as it revolves around the Sun, we can use the concept of gravitational force and centripetal force. Here’s a step-by-step solution:

### Step 1: Understand the Forces Involved
Jupiter is held in its orbit around the Sun by the gravitational force exerted by the Sun. This gravitational force also acts as the centripetal force required to keep Jupiter in its circular orbit.

### Step 2: Write the Formula for Gravitational Force
The gravitational force \( F_g \) between two masses (the Sun and Jupiter) is given by:
\[
