Explanation:
The net force would be upwards since the kangaroo would have to overcome gravity to jump
Answer:
Energy stored in the capacitor is
Explanation:
It is given that,
Charge, 
Potential difference, V = 36 V
We need to find the potential energy is stored in the capacitor. The stored potential energy is given by :

U = 0.000027 J

So, the potential energy is stored in the capacitor is
. Hence, this is the required solution.
