Does anyone know how to answer this question?

The circuit below the resistance of resistor R 1 is exactly 5 times larger than R 2. The work done in R 1 after a certain amount of time t is W 1 =10J.

Circuit diagram showing a battery of voltage V connected in parallel to two resistors of resistances R1 and R2.

Figure 1: Two resistors in parallel across a battery.

What is the value of W 2 the work done in R 2, after the same amount of time t? Give your answer to 2 significant figures.

Start by writing down expressions for the power dissipated in each resistor and then see if you can eliminate the unknown quantities by taking ratio and using relationship between resistances of R1 and R2.
